A 5.7 magnitude earthquake killed at least three people and collapsed 21 buildings including a hotel in eastern Turkey late on Wednesday, state-run TRT television reported.
More people are believed to have been trapped under the rubble, it said, adding rescue teams were trying to find possible survivors.
The quake occurred at 1923 GMT, with the epicentre in the Edremit district, some 15 kilometres (nine miles) from the Van province, according to the Istanbul-based Kandilli Observatory.

Nine planes carrying almost 300 rescuers were dispatched to the quake region, said TRT.
The region bore the brunt of the deadly 7.2 magnitude earthquake on October 23, which killed more than 600 people. Media reports said the collapsed buildings were already damaged in that quake.
One of the collapsed buildings is a six-storey hotel in the Van city centre, NTV television said. The hotel was mostly occupied by journalists and teams from the Turkish Red Crescent.
Television footage showed rescue teams at the scene, trying to recover survivors.
The local media, citing data from the Kandilli Observatory, measured the quake as 5.6 but it was of 5.7 magnitude according to the US Geological Survey.
"It would be premature to say if it is an aftershock or an earthquake," Kandilli Observatory Director Professor Mustafa Erdik told NTV.
