Spain is reeling from its worst flooding in decades, after a year’s worth of rain fell in just hours this week in the country’s southern and eastern regions.

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.

Spain’s King Felipe and Queen Letizia were pelted with mud by crowds during their visit to the region last week, as anger fermented among communities who said they felt abandoned by authorities in the wake of the natural disaster, with troops and police deployed to assist communities in affected areas.
