At least 22 people have died and more than 1,000 are injured after a 6.8-magnitude earthquake rocked eastern Turkey.
Rescue teams from neighbouring areas in the region worked throughout the night to try and find those still trapped by the tremor in Gezin, in eastern Elazig.
At least 30 people are still thought to be trapped inside collapsed structures, Interior Minister Suleyman Soylu said.
Some 30 buildings had collapsed from the quake, according to Murat Kurum, the environment minister.
Turkish president Recep Tayyip Erdogan said efforts were being made to "ensure that the earthquake that occurred in Elazig and was felt in many areas is overcome with the least amount of loss".
The quake struck at 8.55pm local time (5.55pm GMT) and was followed but aftershocks, the strongest measuring with magnitudes 5.4 and 5.1
Elazig is some 465 miles east of the capital, Ankara.
People whose homes were damaged or were too afraid to go indoors were being moved to student dormitories or sports centre amid freezing conditions.
The quake affected not only Turkey but also Syria, Georgia and Armenia.
NTV said the earthquake was felt in several Turkish areas and sent people running outdoors in panic.
Turkey sits on top of two major fault-lines and earthquakes are frequent. Two strong earthquakes struck north-west Turkey in 1999, killing around 18,000 people.
