Rescuers are racing to find survivors in the rubble of thousands of buildings brought down by a 7.8 magnitude earthquake and multiple aftershocks that struck eastern Turkey and neighboring Syria.
The death toll rose to more than 5,000. Countries around the world dispatched teams to assist in the rescue efforts, and Turkey's disaster management agency said more than 24,400 emergency personnel were now on the ground.
But with such a wide swath of territory hit by Monday's earthquake and nearly 6,000 buildings confirmed to have collapsed in Turkey alone, their efforts were spread thin.
Attempts to reach survivors were also impeded by temperatures below freezing and close to 200 aftershocks, which made the search through unstable structures perilous.
