At least 270 people have been killed and more than 1,000 injured following a 7.2-magnitude earthquake that rocked eastern Turkey. Rescuers worked through the night, using cranes and shovels to clear piles of debris and rubble in the hopes of locating survivors. The city of Ercis, near the Iran border, was hardest hit with roughly 80 multistory buildings collapsing to the ground.
