The 7.8 magnitude earthquake struck at 04:17 local time (01:17 GMT) at a depth of 17.9km (11 miles) near the Turkish city of Gaziantep. Twelve hours later, a second quake, which was nearly as large, struck 130km (80 miles) to the north.
Some Aleppo residents told Reuters they have nowhere to go, either because their homes have been destroyed or because they are afraid of further quakes.
