Balkan floods: Fears of new surge on Serbia's River Sava

Emergency workers in Serbia are preparing for a "flood wave" on one of the country's main rivers.
Water levels on the River Sava are expected to peak later on Sunday, threatening the country's biggest power plant.
It comes after the worst floods in the Balkans for decades left at least 35 dead and forced tens of thousands of people to flee their homes.
