VALENCIA, Spain: Spanish authorities on Thursday told people in flood-stricken regions to stay at home as rescuers raced to find survivors in the rare disaster that has left at least 158 dead. Spain began three days of mourning as rescuers with drones scoured towns devastated by the floods that hit the region around the eastern city of Valencia particularly hard. “Please, stay at home... follow the calls of the emergency services,” pleaded Prime Minister Pedro Sanchez.
