At least 20,426 people were injured after the devastating earthquakes, which destroyed 5,775 buildings, the AFAD said.

A magnitude 7.7 earthquake struck Turkey's southern province of Kahramanmaras at 4:17 a.m. local time (0117 GMT), followed by a magnitude 6.4 quake a few minutes later in the country's southern province of Gaziantep and a magnitude 7.6 earthquake at 1:24 p.m. local time (1024 GMT) in the Kahramanmaras Province.

Turkish President Recep Tayyip Erdogan on Monday declared seven days of national mourning for the victims.
