A powerful 7.8 magnitude earthquake rocked southeastern Turkey and northern Syria early Monday, toppling hundreds of buildings and killing more than 4,000 people. Hundreds were still believed to be trapped under rubble, and the toll was expected to rise as rescue workers searched mounds of wreckage in cities and towns across the area.
