Sarai Sierra, the New York mother who disappeared in Turkey while on a solo trip, took several side excursions out of the country, but stayed in contact with her family the entire time, a family friend told ABC News.
Turkish media reported today that police were trying to establish why Sierra visited Amsterdam and Munich. Police were also trying to establish the identity of a man Sierra, 33, was chatting with on the Internet, according to local media.
Rachel Norman, a family friend, said the man was a group tour guide from the Netherlands and said Sierra stayed in regular touch with her family in New York.
Steven Sierra, Sarai's husband, and David Jimenez, her brother, arrived in Istanbul today to aid in the search.
The men have been in contact with officials from the U.S. consulate in the country and plan to meet with them as soon as they open on Tuesday, Norman said.
After that, she said Sierra and Jimenez would meet with Turkish officials to discuss plans and search efforts.

Sarai Sierra was supposed to fly back to the United States on Jan. 22, but she never showed up for her flight home.
Her two boys, ages 11 and 9, have not been told their mother is missing.
Sierra, an avid photographer, left New York on Jan. 7. It was her first overseas trip, and she decided to go ahead after a friend had to cancel, her family said.
"It was her first time outside of the United States, and every day while she was there she pretty much kept in contact with us, letting us know what she was up to, where she was going, whether it be through texting or whether it be through video chat, she was touching base with us," Steven Sierra told ABC News before he departed for Istanbul.
But when it came time to pick her up from Newark Liberty International Airport in New Jersey, Sierra wasn't on board her scheduled flight.
Steven Sierra called United Airlines and was told his wife had never boarded the flight home.
Further investigation revealed she had left her passport, clothes, phone chargers and medical cards in her room at a hostel in Beyoglu, Turkey, he said.
The family is suspicious and said it is completely out of character for the happily married mother, who met her husband in church youth group, to disappear.
The U.S. Embassy in Turkey and the Turkish National Police are involved in the investigation, WABC-TV reported.
"They've been keeping us posted, from my understanding they've been looking into hospitals and sending out word to police stations over there," Steven Sierra said. "Maybe she's, you know, locked up, so they are doing what they can."
The US president could be poised to approve the doubling of imports of tar sands oil, one of the filthiest fuels on Earth
FACED with rising anger from environmentalists last year over his plans for a transcontinental pipeline to deliver treacly Canadian tar sands to Texas oil refineries on the Gulf of Mexico, the CEO of TransCanada, Russ Girling, expressed surprise. After all, his company had laid 300,000 kilometres of such pipes across North America. "The pipeline is routine. Something we do every day," he told Canadian journalists.
But that's the point. It is routine. The oil industry does do it every day. And if it carries on, it will wreck the world.
We need not rely on climate-changing fossil fuels. Alternative energy technologies are available. But fossil fuels, and the pipelines and other 20th-century infrastructure that underpin them, have created what John Schellnhuber, director of Germany's Potsdam Institute for Climate Impact Research, describes in a new paper as "lock-in dominance" (PNAS, DOI: 10.1073/pnas.1219791110). Even though we know how harmful it is, the "largest business on Earth" has ossified and is proving immovable, he says.
The question is how to break the lock and let in alternatives. Schellnhuber, a wily and worldly climate scientist, has an idea, to which I will return. But first the tar-sands pipeline, known as Keystone XL in the parlance of outsize clothing. Proponents say it would create jobs and improve US energy security. But for environmentalists in the US, the decision - due any time - on whether it should go ahead is a touchstone for Barack Obama's willingness to confront climate change in his second term.
Superficially, Keystone XL doesn't look like a huge deal. Since 2010, there has been a cross-border pipe bringing oil from tar sands in northern Alberta to the US Midwest. But this second link would double capacity and deliver oil to the refineries of the Gulf for global export. It looks like the key to a planned doubling of output from one of the world's largest deposits of one of the world's dirtiest fuels. And because the pipe would cross the US border, it requires state department and presidential sign-off.
Environmentalists are up in arms. They fear leaks. No matter what its sponsors suggest, this is no ordinary pipeline. The tar-sands oil - essentially diluted bitumen - is more acidic than regular oil and contains more sediment and moves at higher pressures. Critics say it risks corroding and grinding away the insides of the pipes. The US National Academy of Sciences has just begun a study on this, but its findings will probably be too late to influence Obama.
If there is a leak, clean-up will be difficult, as shown by the messy, protracted and acrimonious attempt to cleanse the Kalamazoo river in Michigan after tar-sands oil oozed into it in 2010.
To make matters worse, the pipeline would cross almost the entire length of the Ogallala aquifer, one of the world's largest underground water reserves, from South Dakota to Texas. Ogallala is a lifeline for the dust-bowl states of the Midwest. While TransCanada has agreed to bypass the ecologically important Sand Hills of Nebraska, where the water table is only 6 metres below the surface in places, a big unseen spill could still be disastrous.
Climate change is still the biggest deal. Extracting and processing tar sands creates a carbon footprint three times that of conventional crude. Obama would rightly lose all environmental credibility if he were to approve a scheme to double his country's imports of this fossil-fuel basket case. Yet he may do it. Why? Because of fossil-fuel lock-in. Changing course is hard. Really hard.
Part of the reason for the lock-in is the vast infrastructure dedicated to sustaining the supply of coal, oil and gas. There is no better symbol of that than a new pipeline. Partly it is political. Nobody has more political muscle than the fossil fuel industry, especially in Washington. And partly it is commercial. As Schellnhuber puts it: "Heavy investments in fossil fuels have led to big profits for shareholders, which in turn leads to greater investments in technologies that have proven to be profitable."
The result is domination by an outdated energy system that stifles alternatives. The potential for a renewable energy revolution is often compared to that of the IT revolution 30 years ago. But IT had little to fight except armies of clerks. Schellnhuber compares this lock-in to the synapses of an ageing human brain so exposed to repetitious thought that it "becomes addicted to specific observations and impressions to the exclusion of alternatives". Or, as Girling puts it, new pipelines become "routine".
What might free us from this addiction? With politicians weak, an obvious answer is to hold companies more financially accountable for environmental damage, including climate change. But Schellnhuber says this won't be enough unless individual shareholders become personally liable, too.
Here, he says, the problem is the public limited company (PLC), or publicly traded company in the US, which insulates shareholders from the consequences of decisions taken in their name. Even if their company goes bankrupt with huge debts, all they lose is the value of their shares. The PLC was invented to promote risk-taking in business. But it can also be an environmental menace, massively reducing incentives for industries to clean up their acts.
"If shareholders were held liable," he says, "then next time they might consider the risk before investing or reinvesting." More importantly, it could prevent us being locked into 20th century technologies that are quite incapable of solving 21st century problems. Fat chance, many might say. But just maybe Keystone XL and its uncanny ability to draw global attention will help catalyse growing anger at the environmental immunity of corporate shareholders.

WELLINGTON: New Zealand's Fonterra, the world's largest dairy exporter, said Monday that its milk was "100 percent" safe to drink despite tests finding trace elements of an agricultural chemical in milk powder.
Fonterra, which reported revenues of NZ$19.8 billion (US$16.6 billion) in the 2012 financial year, said tests had revealed low levels of dicyandiamide (DCD) in some milk samples.
Chief executive Theo Spierings said the DCD levels were 100 times lower than those permitted under European standards and the company was taking steps to reassure international consumers that there were no safety issues.
"Everything that has been exported out of New Zealand is 100 percent safe for consumption," he told Radio New Zealand.
He said suppliers of DCD, which is used to reduce greenhouse gases from dairy herds, had voluntarily agreed to suspend sales of the chemical last week.
Fonterra is sensitive about milk contamination after a partially owned Chinese subsidiary, Sanlu Group, was embroiled in a scandal involving melamine-tainted baby formula in 2008 that killed at least six infants and made 300,000 more ill.
Spierings said Fonterra was in touch with authorities in key markets in Asia about the latest findings.
"We are in contact with Chinese authorities, with Taiwanese authorities and these authorities are adopting the same standard as what we are talking about for these products," he said.
"We will do testing and they will do testing."
With the dairy industry contributing about 25 percent of New Zealand's exports, Prime Minister John Key was keen to stress that the country's milk was safe in order to avoid an overreaction by consumers.
"You'd have to drink the equivalent of a swimming pool full of milk to have any issues whatsoever," he told commercial radio.
"Of course in international markets, which are fragile, there's always concern (about consumer fears)."
Cell phones left in the club ring, go unanswered amid the ruins
The club's license had expired in August and had not been renewed
At least 80 of those killed were students at the Federal University of Santa Maria
Are you there? Share your story.
Santa Maria, Brazil (CNN) -- Workers combing through the charred wreckage of Kiss nightclub in southern Brazil on Sunday encountered the eerie sound of ringing cell phones.
Glauber Fernandes, a reporter from CNN affiliate Band News, explains.
"It was a really complicated scene. A lot of smoke, a lot of shoes that was left, cell phones, because everybody tried to get out of there running," he said. "While we were there, we saw the cell phones were ringing. It was parents, friends, trying to know about what was happening and nobody was answering."
A fire swept through the packed, popular nightclub in Santa Maria early Sunday, killing at least 233 people -- enough to fill a large plane -- Brazilian Health Minister Alexandro Padilha told reporters. Of those, 185 have been identified so far.
Many apparentlydied from smoke inhalation. Others were trampled in the rush for the exits, one security guard told Band News.
More than 90 people were hospitalized, Padilha said, including 14 patients with severe burns.
Deadly blazes: Nightclub tragedies in recent history
About 2,000 people were inside the club when the fire broke out -- double the maximum capacity of 1,000, said Guido de Melo, a state fire official.
Investigators have received preliminary information that security guards stopped people from exiting the club, he told Globo TV.
"People who were inside the facility informed us ... that security guards blocked the exit to prevent people there from leaving, and that's when the crowd starting panicking, and the tragedy grew worse," he said.
The fire started "from out of nowhere" on a stage at the club and quickly spread to the ceiling, witness Jairo Vieira told Band News.
"People started running," survivor Luana Santos Silva told Globo TV. "I fell on the floor."
There was a pyrotechnics show going on inside the club when the fire started. Authorities stopped short of blaming it for the blaze, saying the cause was still under investigation.
The Kiss nightclub is popular with young people in Santa Maria, which is home to a number of universities and colleges, including the Federal University of Santa Maria. At least 80 of those killed Sunday were students at that school, it said.
The blaze broke out during a weekend when students were celebrating the end of summer. Many universities are set to resume classes on Monday.
Video from the scene showed firefighters shooting streams of water at the club and shirtless men trying to break down a wall with axes.
Smoke billowed outside the front of the building as the stench of fire filled the air, said Max Muller, who was riding by on his motorbike when he saw the blaze.
Muller recorded video of a chaotic scene outside the club, which showed emergency crews tending to victims and dazed clubgoers standing in the street. Bodies lay on the ground beside ambulances.
Friends who were inside the club told him that many struggled to find the exits in the dark. Muller, who was not inside the club Sunday morning but has been there twice before, said there were no exit signs over the doors. It is rare to see such signs in Brazilian clubs.
Valderci Oliveira, a state lawmaker, told Band News that he saw piles of bodies in the club's bathroom when he arrived at the scene hours after the blaze. It looked "like a war zone," he said.

Police told Band News that 90% of the victims were found in that part of the club.
The roof collapsed in several parts of the building, trapping many inside, said Fernandes, the reporter from Band News.
For others, escaping was complicated by the fact that guards initially stopped people from leaving, he said, echoing comments from the state fire official.
"Some guards thought at first that it was a fight, a huge fight that happened inside the club and closed the doors so that the people could not leave without paying their bills from the club," Fernandes said.
The deadly fire is sure to shine a spotlight on safety in Brazil, which is set to host the World Cup next year and the Olympics in 2016.
Many wept as they searched for information outside a local gymnasium where bodies were taken for identification later Sunday. Inside, Brazilian President Dilma Rousseff met with family members and friends as they waited on bleachers for word of their loved ones.
Rousseff became teary-eyed as she spoke of the fire to reporters in Chile earlier Sunday. She had been attending a regional summit there, but cut short the trip and returned to Brazil early to deal with the aftermath of the tragedy.
"The Brazilian people are the ones who need me today," she said. "I want to tell the people of Santa Maria in this time of sadness that we are all together."
The fire started around 2 a.m. after the acoustic insulation in the Kiss nightclub caught fire, said Civil Defense Col. Adilomar Silva.
An accordionist who had been performing onstage with a band when the blaze broke out was among the dead, drummer Eliel de Lima told Globo TV.
Police were questioning the club's owner and interviewing witnesses as part of an investigation into what caused the blaze, state-run Agencia Brasil reported.
The club's license had expired in August and had not been renewed, local fire official Moises da Silva Fuchs told Globo TV.
The incident called to mind a 2003 nightclub fire in Rhode Island where pyrotechnics used by the heavy metal band Great White ignited a blaze that killed 100 people.
Pyrotechnics were also involved in a 2004 nightclub fire in Argentina that killed 194 people and a 2009 explosion at a nightclub in Russia that left more than 100 dead.

SANTA MARIA, Brazil A fast-moving fire roared through a crowded, windowless nightclub in southern Brazil early Sunday, filling the air in seconds with flames and a thick, toxic smoke that killed more than 230 panicked partygoers, many of whom were caught in a stampede to escape.
Inspectors believe the blaze began when a band's small pyrotechnics show ignited foam sound insulating material on the ceiling, releasing a putrid haze that caused scores of university students to choke to death. Most victims died from smoke inhalation rather than burns in what appeared to be the world's deadliest nightclub fire in more than a decade.
The Federal University of Santa Maria confirmed to CBS News that 101 of its students were among the dead.
Survivors and a police inspector, Marcelo Arigony, said security guards briefly tried to block people from exiting the club. Brazilian bars routinely make patrons pay their entire tab at the end of the night before they are allowed to leave.
But Arigony said the guards didn't appear to block fleeing patrons for long. "It was chaotic and it doesn't seem to have been done in bad faith, because several security guards also died," he told The Associated Press.
Later, firefighters responding to the blaze initially had trouble getting inside the Kiss nightclub because of "a barrier of bodies blocking the entrance," Guido Pedroso Melo, commander of the city's fire department, told the O Globo newspaper.
Authorities said band members who were on the stage when the fire broke out later talked with police and confirmed they used pyrotechnics during their show.
Police inspector Sandro Meinerz, who coordinated the investigation at the nightclub, said one band member died after escaping because he returned inside the burning building to save his accordion. The other band members escaped alive because they were the first to notice the fire.

More than 200 die in Brazil nightclub fire
"It was terrible inside -- it was like one of those films of the Holocaust, bodies piled atop one another," said Meinerz. "We had to use trucks to remove them. It took about six hours to take the bodies away."
Television images from Santa Maria, a university city of about 260,000 people, showed black smoke billowing out of the Kiss nightclub as shirtless young men who attended the university party joined firefighters using axes and sledgehammers to pound at the hot-pink exterior walls, trying to reach those trapped inside.
Bodies of the dead and injured were strewn in the street and panicked screams filled the air as medics tried to help. There was little to be done; officials said most of those who died were suffocated by smoke within minutes.
Within hours, a community gym was a horror scene, with body after body lined up on the floor, partially covered with black plastic as family members identified kin.
Outside the gym, police held up personal objects -- a black purse, a blue high-heeled shoe -- as people seeking information on loved ones crowded around, hoping not to recognize anything being shown them.
Teenagers sprinted from the scene after the fire began, desperately seeking help. Others carried injured and burned friends away in their arms. Many of the victims were under 20 years old, including some minors. About half of those killed were men, about half women.
The party was organized by students from several academic departments from the Federal University of Santa Maria. Such organized university parties are common throughout Brazil.
"There was so much smoke and fire, it was complete panic, and it took a long time for people to get out, there were so many dead," survivor Luana Santos Silva told the Globo TV network.
The fire spread so fast inside the packed club that firefighters and ambulances could do little to stop it, Silva said.
Another survivor, Michele Pereira, told the Folha de S. Paulo newspaper that she was near the stage when members of the band lit some sort of flare that started the conflagration.
"The band that was onstage began to use flares and, suddenly, they stopped the show and pointed them upward," she said. "At that point, the ceiling caught fire. It was really weak, but in a matter of seconds it spread."
Guitarist Rodrigo Martins told Radio Gaucha that the band, Gurizada Fandangueira, started playing at 2:15 a.m. "and we had played around five songs when I looked up and noticed the roof was burning."
"It might have happened because of the Sputnik, the machine we use to create a luminous effect with sparks. It's harmless, we never had any trouble with it," he said. "When the fire started, a guard passed us a fire extinguisher, the singer tried to use it but it wasn't working."
He confirmed that accordion player Danilo Jacques, 28, died, while the five other members made it out safely.
Police Maj. Cleberson Braida Bastianello said by telephone that the toll had risen to 233 with the death of a hospitalized victim. He said earlier that the death toll was likely made worse because the nightclub appeared to have just one exit through which patrons could exit.
Officials earlier counted 232 bodies that had been brought for identification to a gymnasium in Santa Maria, which is located at the southern tip of Brazil, near the borders with Argentina and Uruguay.
Federal Health Minister Alexandre Padhilha told a news conference that most of the 117 people treated in hospitals had been poisoned by gases they breathed during the fire. Only a few suffered serious burns, he said.
Brazil President Dilma Rousseff arrived to visit the injured after cutting short her trip to a Latin American-European summit in Chile.
"It is a tragedy for all of us," Rousseff said.
Most of the dead apparently were asphyxiated, according to Dr. Paulo Afonso Beltrame, a professor at the medical school of the Federal University of Santa Maria who went to the city's Caridade Hospital to help victims.
Beltrame said he was told the club had been filled far beyond its capacity.
Survivors, police and firefighters gave the same account of a band member setting the ceiling's soundproofing ablaze, he said.
"Large amounts of toxic smoke quickly filled the room, and I would say that at least 90 percent of the victims died of asphyxiation," Beltrame told the AP.
"The toxic smoke made people lose their sense of direction so they were unable to find their way to the exit. At least 50 bodies were found inside a bathroom. Apparently they confused the bathroom door with the exit door."
In the hospital, the doctor "saw desperate friends and relatives walking and running down the corridors looking for information," he said, calling it "one of the saddest scenes I have ever witnessed."
Rodrigo Moura, identified by the newspaper Diario de Santa Maria as a security guard at the club, said it was at its maximum capacity of between 1,000 and 2,000, and partygoers were pushing and shoving to escape.
Santa Maria Mayor Cezar Schirmer declared a 30-day mourning period, and Tarso Genro, the governor of the southern state of Rio Grande do Sul, said officials were investigating the cause of the disaster.
The blaze was the deadliest in Brazil since at least 1961, when a fire that swept through a circus killed 503 people in Niteroi, Rio de Janeiro.
Sunday's fire also appeared to be the worst at a nightclub since December 2000, when a welding accident reportedly set off a fire at a club in Luoyang, China, killing 309.
In 2004, at least 194 people died in a fire at an overcrowded nightclub in Buenos Aires, Argentina. Seven members of a band were sentenced to prison for starting the flames.
A blaze at the Lame Horse nightclub in Perm, Russia, killed 152 people in December 2009 after an indoor fireworks display ignited a plastic ceiling decorated with branches.
Similar circumstances led to a 2003 nightclub fire that killed 100 people in the United States. Pyrotechnics used as a stage prop by the 1980s rock band Great White set ablaze cheap soundproofing foam on the walls and ceiling of a Rhode Island music venue.
The band performing in Santa Maria, Gurizada Fandangueira, plays a driving mixture of local Brazilian country music styles. Guitarist Martin told Radio Gaucha the musicians are already seeing hostile messages.
"People on the social networks are saying we have to pay for what happened," he said. "I'm afraid there could be retaliation."
The bodies of the young college students were found piled up just inside the entrance of the Kiss nightclub, among more than 230 people who died in a cloud of toxic smoke after a blaze enveloped the crowded locale within seconds and set off a panic.
Hours later, the horrific chaos had transformed into a scene of tragic order, with row upon row of polished caskets of the dead lined up in the community gymnasium in the university city of Santa Maria. Many of the victims were under 20 years old, including some minors.
As the city in southern Brazil prepared to bury the 233 people killed in the conflagration caused by a band's pyrotechnic display, an early investigation into the tragedy revealed that security guards briefly prevented partygoers from leaving through the sole exit. And the bodies later heaped inside that doorway slowed firefighters trying to get in.
"It was terrible inside — it was like one of those films of the Holocaust, bodies piled atop one another," said police inspector Sandro Meinerz. "We had to use trucks to remove them. It took about six hours to take the bodies away."
Survivors and another police inspector, Marcelo Arigony, said security guards briefly tried to block people from exiting the club. Brazilian bars routinely make patrons pay their entire tab at the end of the night before they are allowed to leave.

Police inspectors said they think the source of the blaze was a band's small pyrotechnics show. The fire broke out sometime before 3 a.m. Sunday and the fast-moving fire and toxic smoke created by burning foam sound insulation material on the ceiling engulfed the club within seconds.
Authorities said band members who were on the stage when the fire broke out later talked with police and confirmed they used pyrotechnics during their show.
Meinerz, who coordinated the investigation at the nightclub, said one band member died after escaping because he returned inside the burning building to save his accordion. The other band members escaped alive because they were the first to notice the fire.

"There was so much smoke and fire, it was complete panic, and it took a long time for people to get out, there were so many dead," she said.
Most victims died from smoke inhalation rather than burns. Many of the dead, about equally split between young men and women, were also found in the club's two bathrooms, where they fled apparently because the blinding smoke caused them to believe the doors were exits.
There were questions about the club's operating license. Police said it was in the process of being renewed, but it was not clear if it was illegal for the business to be open. A single entrance area about the size of five door spaces was used both as an entrance and an exit.
FEATHERY cirrus clouds are beautiful, but when it comes to climate change, they are the enemy. Found at high-altitude and made of small ice crystals, they trap heat - so more cirrus means a warmer world. Now it seems that, by destroying cirrus, we could reverse all the warming Earth has experienced so far.
In 2009, David Mitchell of the Desert Research Institute in Reno, Nevada, proposed a radical way to stop climate change: get rid of some cirrus. Now Trude Storelvmo of Yale University and colleagues have used a climate model to test the idea.
Storelvmo added powdered bismuth triiodide into the model's troposphere, the layer of the atmosphere in which these clouds form. Ice crystals grew around these particles and expanded, eventually falling out of the sky, reducing cirrus coverage. Without the particles, the ice crystals remained small and stayed up high for longer.
The technique, done on a global scale, created a powerful cooling effect, enough to counteract the 0.8 °C of warming caused by all the greenhouse gases released by humans (Geophysical Research Letters, DOI: 10.1002/grl.50122).
But too much bismuth triiodide made the ice crystals shrink, so cirrus clouds lasted longer. "If you get the concentrations wrong, you could get the opposite of what you want," says Storelvmo. And, like other schemes for geoengineering, side effects are likely - changes in the jet stream, say.
Different model assumptions give different "safe" amounts of bismuth triiodide, says Tim Lenton of the University of Exeter, UK. "Do we really know the system well enough to be confident of being in the safe zone?" he asks. "You wouldn't want to touch this until you knew."
Mitchell says seeding would take 140 tonnes of bismuth triiodide every year, which by itself would cost $19 million.

MADRID: Anger over a long list of corruption scandals implicating bankers, politicians and even members of the royal family is on the rise in recession-hit Spain, putting the spotlight on the failure of the country's democracy to tackle the issue.
At demonstrations against government austerity measures, chants against alleged shady deals by Spain's elite are as common as those venting anger at tax hikes and spending cuts to social services and public workers' pay.
Around 200-300 elected officials out of more than 50,000 in the country are currently implicated in corruption cases in regions governed both by both the left and the right, said the head of the Spanish branch of anti-corruption watchdog Transparency International, Jesus Lizcano.
"While small, it is a significant percentage and is a bit alarming and calls for an urgent response on the part of political parties," he said.
With taxpayers reeling under austerity measures and a record unemployment rate of 26 percent, many feel that "the political class is not able to resolve the economic crisis, that it is useless, and that they protect each other", said University of Santiago de Compostela political science professor Anton Losada.
The latest corruption scandal to make headlines involves Prime Minister Mariano Rajoy's centre-right Popular Party, whose popularity has plunged since it won a November 2011 election in a landslide.
Daily newspaper El Mundo reported on January 18 that former Popular Party treasurer Luis Barcenas distributed envelopes containing thousands of euros to party officials on top of their declared salaries.
It said the money came from commissions collected from construction firms, insurance companies and anonymous donors.
Top Popular Party officials have strongly denied any involvement in the affair and have kept their distance from Barcenas, who reportedly had up to 22 million euros ($29 million) in Swiss bank accounts until 2009.
Hundreds of people protested, chanting "thieves" and "shame", near the headquarters of the Popular Party in central Madrid on the day El Mundo published its allegations against Barcenas.
Corruption scandals have even hurt the popularity of King Juan Carlos after one implicated a member of his family.
His son-in-law Inaki Urdangarin was accused last year of embezzling public money paid by regional governments to a charitable organisation based in Mallorca which he chaired from 2004 to 2006.
"During the past three weeks people have been very, very, very angry, there has been a growing social alarm and it is very important that politicians take this issue seriously," said Lizcano.
The corruption scandals have shaken Spaniards' faith in politicians nearly four decades after the death of dictator General Francisco Franco in 1975 paved the way for the country's return to democracy.
Three in four Spaniards think political corruption is rising in the country and that politicians get better treatment in the courts than regular citizens, according to a poll published in conservative newspaper ABC on January 20.
Rajoy has ordered an internal investigation into the finances of the party and has vowed to take action if any wrongdoing is uncovered.
Last year, his government vowed to table a law on political transparency and earlier this month it proposed an anti-corruption pact with other parties.
After Franco's death the country's 17 autonomous communities were given broad powers with little oversight over their finances, which are largely blamed for the country's bloated public deficit.
"There is an urgent need for parties to publish their accounts and their sources of financing," as in other European nations, said Lizcano.
He said there is too much involvement by politicians in institutions such as the courts and regional savings banks.
Popular anger was fuelled this month when Spanish telecom giant Telefonica hired Rodrigo Rato, a former head of the International Monetary Fund, as an advisor just weeks after he appeared in court in a fraud case involving bailout-out bank Bankia, which he once headed.
Lizcano has little faith that the government will follow through on its vow to step up the fight against corruption.
New York Mayor Michael Bloomberg graduated from Johns Hopkins University in 1964.
STORY HIGHLIGHTS
NYC mayor's latest gift to John Hopkins is $350 million
That makes for a total of $1.1 billion over 45 years
Donation will go toward a "transformational" academic initiative
Bloomberg took out loans to attend Hopkins in the 1960s
(CNN) -- A kid raised in a middle-class Boston suburb, Michael Bloomberg took out loans to pay for his tuition at Johns Hopkins University and worked as a parking lot attendant.
He learned early to pay it forward.
Bloomberg's first gift to his alma mater was a whopping $5 in 1965, a year after he graduated with a bachelor's degree in engineering.
Fast forward to Saturday, when the Baltimore university announced Bloomberg has now given a total of $1.1 billion. The latest commitment came in the form of a cool $350 million toward a "transformational" initiative aimed at cross-discipline solutions to societal problems.
In a statement, Johns Hopkins said Bloomberg, a former trustee, is believed to be the first person to ever reach the $1 billion level of giving to a single U.S. institution of higher education.
The university's Twitter feed was aglow with information on the gift. One tweet heralded the announcement with the words, "Big News," which might have been an understatement.
Among other things, the donation will fund 2,600 Bloomberg Scholarships over 10 years and 50 distinguished scholars.
Of the $350 million, $100 million will go toward "need-based financial aid" for undergraduate students.
"Johns Hopkins University has been an important part of my life since I first set foot on campus more than five decades ago," Bloomberg said in the press release. "Each dollar I have given has been well-spent improving the institution and, just as importantly, making its education available to students who might otherwise not be able to afford it."
The remarkable tally speaks to the generosity and success of New York City's mayor, who grew a business empire after leaving Baltimore. He will turn 71 on Valentine's Day.
Bloomberg earned an MBA from Harvard Business School. He was hired by the Wall Street firm Salomon Brothers in 1966, according to his biography on NYC's website.
After he was let go from Salomon when it was acquired in 1981, the budding entrepreneur used his information systems expertise to launch Bloomberg LP, which provided advanced computer systems for traders and financial firms. Bloomberg's media interests followed and the company now has more than 15,000 employees worldwide, according to his biography.
Bloomberg eventually devoted his energies to philanthropy and politics. He was elected mayor of the Big Apple in 2001 and has held the office since.
His first $1 million commitment to Johns Hopkins was made in 1984, 20 years after graduation, in honor of his mother, Charlotte.
The university's president, Ronald J. Daniels, said Saturday's announced gift "illustrates Mike's passion for fixing big problems quickly and efficiently. It will ensure not only that Johns Hopkins helps to solve humanity's problems, but also that it leads the world's universities in showing how it should be done."
The mayor's overall giving includes $240 million for capital and infrastructure improvements, $219 million for student financial aid and $336 million for research.
"Giving is only meaningful if the money will make a difference in people's lives," said Bloomberg. "And I know of no other institution that can make a bigger difference in lives around the world through its groundbreaking research -- especially in the field of public health."

CHICAGO Authorities are investigating the shooting deaths of five people in a single day of bloodshed in Chicago.
Police Officer Daniel O'Brien says Saturday's first killing occurred at around 2:15 a.m. on the city's west side when a gunman opened fire on two men who were sitting in a parked car, killing one and wounding the other.
Investigators say a few hours later, someone opened fire on three men near a South Side eatery, killing two of them and wounding the third.
Detectives were called to the scene of another shooting Saturday afternoon in which a man in his 30s and a teenager were shot to death. There had been no arrests.
Chicago's homicide count eclipsed 500 last year for the first time since 2008.
