New storms in Spain have caused school closures and train cancellations two weeks after flash floods in Valencia and other areas killed more than 220 people and destroyed thousands of homes.

The flash floods were caused by heavy rain, which by Wednesday morning had begun "easing off," according to the country's meteorological agency.

Flood-hit towns near the eastern city of Valencia were rushing on Tuesday to clear the sewage system of mud and debris, pile sandbags and cancel school classes as they prepared for another approaching storm.
