"Entire houses have disappeared," says a local mayor in Spain's flood-battered Valencia region. "We don't know if there were people inside."

So far, 205 bodies have been recovered after the floods in Spain. Volunteers are helping clean up thick mud that is covering streets and businesses.

Spain's Mediterranean coast is used to autumn storms that can cause flooding, but this was the most powerful flash flood event in recent memory. Scientists link it to climate change.
