The live coverage of a Turkish news channel in the disaster area is abruptly interrupted by a strong aftershock.
Yuksel Akalan, reporter:
“As we made our way to the rubble to film the search and rescue operations, there were two consecutive aftershocks and noise. The building you see to my left has collapsed. There's a lot of dust. A local resident comes and is covered in dust.”
Yuksel Akalan, reporter:
"A mother takes her children outside."
After the first tremor early Monday morning, there were numerous aftershocks, according to the Turkish disaster agency.
According to reports, some of these were as strong as the first tremor and made rescue work considerably more difficult.
According to preliminary information, at least 2,300 people lost their lives in the Turkish-Syrian border area during the most devastating earth in the region for decades.
The numbers are likely to increase - it is unclear how many people are still trapped under the rubble.
Near the border with Turkey, in north-western Syria, emergency services are feverishly searching for people who have been buried.
In Sarmada, north of Idlib, rescuers were able to salvage a family of three from the rubble.
In the north-west, which was badly hit by the civil war, whole rows of houses have collapsed, the foundations of which have often been damaged by air raids.
Numerous countries announced support, including Germany and war-torn Ukraine.
