An earthquake rescue team dispatched by China's government arrived in Turkey's Adana Airport early on Wednesday, state broadcaster CCTV reported on Wednesday.
As the scale of the disaster became ever more apparent, the death toll looked likely to rise considerably. One U.N. official said thousands of children may have died.
In the Turkish city of Antakya near the Syrian border, where 10-storey buildings had crumbled onto the streets, Reuters journalists saw rescue work being conducted on one out of dozens of mounds of rubble.
