At least 18 buildings, including two hotels, collapsed in eastern Turkey after a 5.7-magnitude quake struck just south of the city of Van near the Iranian border, Turkish state television reported.

TRT Haber news channel said a large number of people were trapped under the buildings and rescue workers could be seen searching through the rubble.

Less than three weeks ago, a 7.6 magnitude quake hit just northeast of Van, killing some 600 people.
