Thousands of rescuers pumped water from submerged buildings, churned through muddy streets and cleared debris on Monday as Spain braced for more deaths from its worst floods in decades.The toll stands at 217 dead and could spike in the coming days as an unknown number of people remain missing. Around 17,000 soldiers, police officers, civil guards and firefighters spent a sixth day distributing aid, repairing infrastructure and searching for bodies using heavy machinery, drones and sniffer dogs.
