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.

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.

Spanish Prime Minister Pedro Sanchez on Monday announced 3.76 billion euros ($4.01 billion) in additional measures to reconstruct the Valencia area after the deadliest flash floods in Spain's modern history.
