Packed into buses, boats and helicopters, carrying nothing but a handful of belongings, tens of thousands of people have fled their homes in Bosnia and Serbia to escape the worst flooding in a century.

Rapidly rising rivers surged into homes, sometimes reaching up to the second floors, sending people climbing to rooftops for rescue. Hundreds were also evacuated in Croatia.

Authorities said on Saturday 25 people had died, but warned the toll could rise. Tens of thousands of homes were left without electricity or drinking water.

Landslides triggered by the floods also raised the risk of injury or death from land mines left over from Bosnia's 1992-95 war. The landslides swept away many of the carefully placed warning signs around the minefields.

Three months' worth of rain fell on the region in three days last week, creating the worst floods since records began 120 years ago.

From the air almost a third of Bosnia, mostly its north-east corner, resembled a huge muddy lake, with houses, roads and rail lines submerged. Admir Malagic, a spokesman for Bosnia's security ministry, said about a million people – more than a quarter of the country's population – lived in the affected area.

"Bosnia is facing a horrible catastrophe," said Bakir Izetbegovic, the chairman of the Bosnian three-man presidency. "We are still not fully aware of actual dimensions of the catastrophe ... we will have to take care of hundreds, thousands of people."

Izetbegovic was touring Maglaj, hard hit by the floods. As the waters mostly withdrew on Saturday, Maglaj was covered in mud and debris, with residents checking damage and bringing furniture out in the streets to dry.

"Everything is destroyed, but we are happy to be alive," said Maglaj resident Zijad Omerovic.

In the eastern Bosnian town of Bijeljina, some 10,000 people were being evacuated on Saturday after the rain-swollen Sava river pushed through flood defences, endangering four villages outside the town.

"We need everything, we are underwater," mayor Mico Micic exclaimed.

In eastern Croatia, the overflowing Sava spread over villages and farm land, sending hundreds fleeing.



Officials in Bosnia said 17 people haddied and more bodies could be found as water receded from dozens of cities. In some places, people had to be rescued by helicopter from their roofs.

Many in Bosnia lost homes they had only just rebuilt after the war, which claimed 100,000 lives and devastated the impoverished country.

In Serbia, eight deaths were reported and emergency crews and soldiers were using boats and helicopters to rescue thousands trapped in the town of Obrenovac, near Belgrade. Authorities also ordered residents of another nearby small town, Baric, to leave immediately on Saturday afternoon. Many hurriedly climbed into buses and military trucks to get away.

Officials said more than 16,000 people have been evacuated from flood-hit regions in Serbia, many finding shelter in schools and sports halls. Lines of mattresses covered the floors of Belgrade schools, with frightened survivors describing unstoppable torrents that surged in a matter of minutes.

Mirjana Senic, who lives in the centre of Obrenovac, said that "we thought we had it pretty bad ... [but] only when they evacuated us and when we actually saw the amount of water in other parts of town did we realise that we were lucky."

The flooding in Obrenovac is threatening the Nikola Tesla power plant, Serbia's biggest. Plant capacity had already been cut after a nearby coal mine was flooded and authorities urged residents to save energy to avoid brown-outs.

Prime minister Aleksandar Vucic told a press conference a new wave of flooding on the Sava would hit on Sunday evening.

"Our primary concern is to protect the power plant," Vucic said. "We are doing all we can."

International help poured into the two nations to support thousands of volunteers. A Russian team joined the rescue efforts in Serbia. Rescue teams from Luxembourg, Slovenia and Croatia were already in Bosnia, and others from the UK, Austria and Macedonia were expected.
