The Croatian authorities have issued an arrest warrant for former Prime Minister Ivo Sanader, soon after he left the country amid a corruption inquiry.
Mr Sanader crossed into Slovenia on Thursday, hours before parliament voted to lift his immunity from prosecution.
He is suspected of abuse of office during his time as prime minister until 2009.
Mr Sanader reportedly denied fleeing from prosecution.
Mexican police have been involved in fierce gun battles with suspected drug traffickers blockading the main roads into Morelia, the capital of Michoacan state.
There has also been fighting in the nearby city of Apatzingan.
At least three people were killed, including an eight-month-old baby apparently caught in the crossfire.
Michoacan, in western Mexico, is a stronghold of a powerful drugs cartel known as La Familia Michoacana.
The five main roads leading in and out of Morelia were blocked by burning cars and buses, police said.
Gunmen fired into the air to force drivers and passengers out of their vehicles before setting them ablaze.
Schools kept children inside their classrooms for their protection, and the city's university was closed, the Mexican newspaper El Universal reported.
Fighting broke out as police moved in to clear the blockades.
The upsurge in violence in Michoacan began on Wednesday when federal police went into the city of Apatzingan to search for suspected La Familia gang members, police said.
They quickly came under fire with automatic weapons, and police reinforcements were also attacked as they drove to assist their colleagues.
Army troops and helicopters were also brought in, and the cartel gunmen retreated, blocking the road behind them with burning vehicles.
One police officer was killed along with two civilians - a baby and a young woman.
Mexico's public security ministry denied local media reports that a police helicopter was shot down during the fighting. Family values La Familia Michoacana is involved in cocaine smuggling to the US along Mexico's Pacific coast as well as the production of the synthetic drug, methamphetamine.
Despite a reputation for ruthless violence, it has always claimed strong links to the community in Michoacan state, and advocates religious and family values.
In recent months the gang has come under growing pressure from the Mexican authorities, with several suspected leaders captured.
It has also been involved in bloody territorial wars with rival cartels.
The cartel was recently reported to have offered to negotiate a truce with the government and disband.
Michoacan is the home state of President Felipe Calderon, and one of the first places where he deployed the army to fight drugs gangs after he took office in 2006.
The fight against malaria and TB in the developing world should not obscure the problems poor countries face with hospital infections, experts say.
A team led by World Health Organization researchers found poorer countries had much higher infection rates than the developed world.
They reviewed 220 previous studies, finding infection rates were three times higher than in the US.
But they said the issue was going largely unnoticed, the Lancet reported.
The team, which also included Professor Sir Liam Donaldson, the former chief medical officer for England, looked at data going back to 1995 on a range of healthcare-associated bugs, including urinary tract, bloodstream and surgical site infections as well as hospital-acquired pneumonia.

Health-care-associated infections in developing countries are a serious issue that is scarcely addressed in the scientific literature”

Researchers found the infection rate in developing countries was 15.5 per 100 patients. In Europe it is 7.1 and in the US, 4.5.
The difference in intensive care infections was even greater. In developing countries, infection rates were 47.9 per 1,000 patient-days, compared to 13.6 in the US. Simple measures The researchers said simple, low cost measures such as better hand hygiene, surveillance and staff education could make a big difference.
Professor Didier Pittet, one of the lead researchers, said: "There can be a misconception that healthcare-associated infections are not often found in developing countries, simply because their healthcare systems are blitzed with other issues that high-income countries have dealt with or controlled long ago."
Dr Victor Rosenthal, of the International Nosocomical Infection Control Consortium, which was set up to tackle hospital infections globally, welcomed the research, saying: "Health-care-associated infections in developing countries are a serious issue that is scarcely addressed in the scientific literature."
He added it was likely the higher infection rates were leading to deaths, longer hospital stays and extra costs and called on steps to be taken to tackle the problems.

Protesters mount last stand
Questions have been raised about police handling of tuition fee protests after a car carrying the Prince of Wales and the Duchess of Cornwall was attacked.
A window was smashed and paint thrown at the vehicle as the royal couple made their way to a central London theatre.
Violent demonstrations spread after MPs voted to increase university tuition fees in England.
Met Police chief Sir Paul Stephenson said there would be a "very serious investigation" into the disturbances.
Mark Pritchard, Conservative MP for The Wrekin, questioned police tactics.
He told the BBC: "We've got 'kettling' that is supposed to confine people in an area to stop violence spilling out to other areas, and clearly it has not worked.
"Therefore, the planning and control and the senior management decisions by the Metropolitan Police over this whole incident need to be looked at."
Sir Paul Stephenson: "Any right minded individual, including peaceful protesters, will condemn what has happened today"
Universities Minister David Willetts said the attacks on the police were "shocking" and the officers caught up in the violence should be supported.
"The police were in very difficult circumstances and they were being tested over hours, often of abuse and attack. I don't think it's for us who were not on the front line like they were to criticise them," he told the BBC.
London Mayor Boris Johnson said it was regretable the heir to the throne could be surrounded by agitators and that people's first instinct was to blame the police.
The National Union of Students (NUS) said the violence had overshadowed the story it wanted to see in the newspapers.
Shane Chowen, vice-president of further education, said: "Not the headlines I wanted. I wanted to see the fact that the coalition government have just trebled tuition fees, sentencing a generation of students to record student debt."
The prince and duchess, who were travelling to the London Palladium for the annual Royal Variety Performance, were unharmed.
Prime Minister David Cameron said it was "shocking and regrettable" that protesters had attacked the prince's car.
Clarence House said the royal couple were safe and had attended the performance as scheduled.
Metropolitan Police Commissioner Sir Paul Stephenson described it as a "very stretching day" for his officers and a "very disappointing day" for London.
"We did everything we could to facilitate peaceful protest and, in reality, whilst I'm sure the vast majority came here to want to protest peacefully, a significant number of people behaved very badly," he said. Backbench rebellion "We want to see people peacefully protesting on the streets of London if that's what they wish to do, but the behaviour is wholly unacceptable and we will now mount a very serious and very detailed investigation to try and identify the perpetrators of the violence."
The former head of royal protection, Dai Davies, told BBC Radio 4's Today programme he was "appalled" by the attack on the royals and surprised by the apparent lack of strategy.
He said: "One of the principles of protection is to have alternative routes and I would have expected there to be at least three different routes.
"I'm surprised, and clearly the commissioner is embarrassed and surprised also, why there isn't better co-ordination - or appears to be - between those in charge of protection and those marshalling and dealing with the riots."
Theresa May condemns the "appalling levels of violence"
The Commons vote mean fees will almost treble to £9,000 a year. The government's majority was cut by three-quarters to 21 in a backbench rebellion. Three ministerial aides resigned.
Only 28 Lib Dem MPs - fewer than half - voted for the government's plans for tuition fees. Six Conservative MPs voted against.
Students from around the UK gathered in London for a day of protests and a rally - with police expecting about 20,000 demonstrators.
In angry scenes, protesters battled with police in Parliament Square. Hundreds were contained on Westminster Bridge for a time by officers.
There were angry clashes as protesters - some throwing missiles - fought to break through police lines.
Riot police had to force back protesters who were smashing windows of the Treasury and the Supreme Court.
Earlier, protesters had largely taken over Parliament Square and pressed against lines of police in front of the Houses of Parliament.

Mounted police were used to control crowds, at one point charging a group of protesters.
Scotland Yard said 12 officers and 43 protesters were injured, and 34 people were arrested.
Supt Julia Pendry said officers had come under sustained attack and condemned "acts of wanton vandalism, wanton violence" by protesters.
Police said there were attacks using "flares, sticks, snooker balls and paint balls".
The Metropolitan Police Authority chairman, London Deputy Mayor Kit Malthouse, defended the tactic of holding of demonstrators in a small area, known as "kettling".
He said: "You either go for dispersal of the crowd, and we've seen that in London in the past, what you then get is groups of protesters ranging through London.
"The other alternative is to contain, and that often calms the crowd down.
"Now, obviously these crowds can be very volatile and people can break away, and that seems to be what's happened."
Home Secretary Theresa May said she "utterly condemned" the violence.
"What we are seeing, the wanton vandalism, smashing of windows, has nothing to do with peaceful protest," she said.
"I have spoken to Paul Stephenson and he has updated me on the appalling levels of violence.
"Attacks on police officers and property show that some of the protesters have no respect for London or its citizens."
She said the "next steps" in relation to the attack on the royal car were down to the police.
The coalition government faced its first major backbench rebellion in the vote.
The package of measures will see fees rising to an upper limit of £9,000 per year - with requirements for universities to protect access for poorer students if they charge more than £6,000 per year.
A US federal jury has convicted three police officers and cleared two over the killing of a man after Hurricane Katrina flooded New Orleans in 2005.
The jury convicted former officer David Warren of manslaughter in the shooting of 31-year-old Henry Glover.
Officer Gregory McRae was convicted of burning Mr Glover's body, while Lt Travis McCabe was convicted of writing a false report on the shooting.
Lt Dwayne Scheuermann and ex-Lt Robert Italiano were acquitted.
The trial was the first in a series of cases against New Orleans police officers for alleged abuses committed in the aftermath of the hurricane, when thousands of desperate people were trapped in the flooded city.
During the trial the five officers described the frantic conditions in New Orleans after the storm struck the city on 29 August 2005.
They told the jury that amid the chaos and with lives at stake, they only had time to investigate the most serious of crimes.
Prosecutors said the storm did not justify the guilty officers' actions but might explain them.
Hurricane Katrina made them believe "no-one was watching and no-one would care about Henry Glover", said prosecuting lawyer Tracey Knight.
The BBC's Iain Mackenzie, in New Orleans, says scrutiny of the city's police force will not end with these verdicts, because a further 13 officers are due to stand trial in other Katrina related cases - among them the murders of several unarmed civilians. Gruesome incident On the day of the hurricane, Mr Glover and Bernard Calloway, a friend of Mr Glover's, pulled up to a police substation at a shopping mall guarded by Warren - who was armed with his own assault rifle.
The men ran to a gate that would have allowed them to enter the building, Warren said, adding that Mr Glover appeared to be holding a gun.
Lt Robert Italiano, shown here embracing his daughter, was acquitted
Warren then explained that he gave the two men commands to stop before shooting Mr Glover in the back from a second-floor balcony.
But Officer Linda Howard, Warren's partner on the day the hurricane struck, told the court it did not appear Mr Glover was armed and that she saw the victim lighting a cigarette while leaning against a vehicle directly before he was shot.
A passing motorist, William Tanner, spotted Mr Glover and Mr Calloway and stopped to help them.
But when the group, along with Mr Glover's brother, reached a school that authorities were using as a base, police ordered the men out at gunpoint, Mr Tanner and Mr Calloway told the jury.
McRae admitted to the court he then drove Mr Tanner's car, once Mr Calloway and Mr Tanner exited the vehicle, from the school to a river levee and set it on fire with Mr Glover's body inside.
McRae said he committed the act because he did not want to see additional dead bodies rot around New Orleans.
