ADANA, Turkiye — Rescuers in Turkiye and 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.

Survivors cried out for help from within mountains of debris as first responders contended with rain and snow. Seismic activity continued to rattle the region, including another jolt nearly as powerful as the initial quake. Workers carefully pulled away slabs of concrete and reached for bodies as desperate families waited for news of loved ones.

"My grandson is 1 1/2 years old. Please help them, please. ... They were on the 12th floor," Imran Bahur wept by her destroyed apartment building in the Turkish city of Adana on Monday.

Tens of thousands who were left homeless in Turkiye and Syria faced a night in the cold. In the Turkish city of Gaziantep, a provincial capital about 33 kilometers (20 miles) from the epicenter, people took refuge in shopping malls, stadiums, mosques and community centers. Turkish President Recep Tayyip Erdogan declared seven days of national mourning.
