Rescuers in Turkey and war-ravaged Syria searched through the frigid night into Tuesday, hoping to pull more survivors from the rubble after a 7.8 magnitude earthquake killed more than 4,000 people and toppled thousands of buildings across a wide region.
Authorities feared the death toll from Monday's pre-dawn earthquake and aftershocks would keep climbing as rescuers looked for survivors among tangles of metal and concrete spread across the region beset by Syria's 12-year civil war and refugee crisis.
