Before and after pictures show devastating effects

Spain is grappling with devastating floods that left more than 200 people dead and dozens missing this week.

Thousands of emergency responders and military personnel have been working on search and rescue operations in flood-affected regions, while locals have begun cleanup efforts and assessing the level of damage.

Further rainfall is expected over the weekend. A rain warning is in effect along the Huelva coast in the southwest and residents are urged to stay at home.

Before and after images show the extent of the damage caused by the flash flood and torrential rain, as they swept away buildings, piled up debris on roads and railways and destroyed bridges.

Across Valencia, the hardest-hit region, cars were washed onto roads, train tracks and tunnels.

A large number of those killed were on the streets, in many cases returning from work, when the flash floods struck.

The above tunnel, which connects the municipalities of Benetusser and Alfafar in Valencia, was blocked by a large number of cars swept away by the water.

Parts of Valencia, the country's third-largest city, received a year's worth of rain in just eight hours on Wednesday.

Dozens of meters of railway tracks have been damaged or completely destroyed, and rail traffic between Madrid and Valencia has been suspended while the tracks are being rebuilt.

Some streets and residential areas were destroyed by flash floods, like here in Letur, southwest of Valencia. The road is completely covered with mud, stones and rubble.

Satellite images give an idea of ​​how violently the water hit the coastal towns and show how much the landscape has changed in the last few days.
