The worst floods in the Balkans for decades are threatening Serbia's main power plant, officials say.
The River Sava has burst its banks in many areas and water levels are expected to peak later on Sunday.
At least 20 people have died in Serbia and Bosnia-Hercegovina after a month's worth of rain fell in three days, and the death toll is expected to rise.
