At least nine people have died in bad weather in Odessa in southwestern Ukraine, according to the rescue service. Among the dead is a child.
In seven hours, almost as much rain came as usually falls in two months, according to Mayor Hennadij Truchanov.
During the night towards Wednesday, hundreds of rescue workers have struggled to evacuate people in the flooded areas, move cars and pump water out of buildings.
The deadly bad weather poses new challenges for the rescue service in Ukraine, which is subjected to daily attacks from Russia. The forecast also warns of continued downpours.
