River Danube freezes over
Such is the cold that the Danube has frozen over. Thick ice has closed hundreds of kilometres of the river. In Bulgaria between 50 and 90 per cent of it is iced up.
Navigation is impossible or restricted in Serbia, Croatia, Bulgaria, Romania, Hungary and Austria, as ice has covered the river or formed dangerous floes in shipping lanes.
Bulgarian authorities, who have banned all navigation on the river, reported 224 vessels stuck in ports. Rescuers in Croatia reached three crew members on a ship trapped in the ice since Friday.
