Torrential rains have caused havoc across central and eastern Europe, killing up to 36 people.
Worst affected is Romania where at least seven elderly people were killed overnight, bringing deaths there to 25.
At least 11 people are reported dead or missing in Switzerland, Austria and Germany where emergency services are struggling to restore basic services.
Thousands of people have been forced to abandon their homes in recent days. Many are still unable to return.
The elderly Romanians were swept away by swollen rivers , AFP news agency reported.
Floods inundated about 1,400 houses in central parts of the country.
Elsewhere in Europe:
- In Bavaria, some flood defences have collapsed, allowing water to flood through streets and into homes; authorities evacuated patients at the city of Neu-Ulm after the Danube burst its banks
- In Bulgaria, where floods have killed at least 20 people and left 14,000 homeless over the past three months, torrential rains flooded the north-western region of Montana
- In Moldova torrential rain has damaged homes and other property near the capital Chisinau
- Torrential rain in Slovenia has washed out roads in several towns in central and eastern districts. Croatia has declared a state of emergency along the Mura river, on the border with Slovenia, where it is shoring up flood defences.
At least four people have died and two are missing in Switzerland, where floods have affected an area stretching from the Bernese Alps to St Gallen in the north-east.

More than 1,000 Swiss have been evacuated, along with hundreds more in Austria and Germany.
In the Swiss capital Bern, the River Aare burst its banks flooding parts of the historic old town.
