Almost the entire length of the river in Serbia has been frozen.
Watch icebreaker in action on frozen Danube River.
“Dozens of smaller boats and floating homes have been damaged or destroyed over the past week along a stretch of the Danube in Belgrade as ice ripped through marinas and moorings.”
One Hungarian icebreaker also managed to get through on the morning of the 18th to break the ice in Croatia.
