The top half of a two-storey house lays on the rubble-strewn ground in tornado-ravaged Joplin, Missouri on May 24, 2011. Rescuers combed through overturned cars and flattened buildings Tuesday hunting for survivors after this Missouri town was struck by one of the strongest tornadoes ever recorded in the US. A massive mile-wide funnel-cloud, with winds of up to 200 miles (320 kilometers) an hour, tore with devastating force through the town of Joplin late Sunday, leaving 116 people dead and hundreds more missing.
