A state of emergency has been declared and residents evacuated after heavy rainfall caused floods in several areas of Bosnia.
In the eastern town of Foca, rescuers used boats to evacuate people as water reached the first floors, officials said.
Schools are closed, half of the town has no electricity, city water can no longer be drunk and in nearby Gorazde the federal army helped the evacuation.
It is still raining throughout the country and authorities warn more rivers – especially in the south – are threatening to burst their banks.
City officials in Foca say the Drina river has not risen as high for the past 104 years.
In neighbouring Serbia hundreds were also evacuated.
In western Serbia, the Drina flooded houses, farming land and roads.
In northern Montenegro some 600 people were evacuated spending the night in a community centre.
