An earthquake with a preliminary magnitude of 5.7 has caused some buildings to collapse in eastern Turkey, it has been reported.
The Dogan news agency said the quake hit the eastern province of Van, more than two weeks after a 7.2 earthquake there killed around 600 people.
Dogan says the latest quake brought down buildings which were damaged in the earlier one.
It was not known if anyone was trapped under debris.
State-run TRT television said the quake brought down a six-storey hotel.
TV footage showed residents and rescuers trying to dig out people believed to be trapped under the debris.
Sky Turk television said the hotel was being used by journalists and aid workers. It was not known how many people were trapped inside.
Hundreds of aftershocks have rocked the region since the 7.2-magnitude earthquake hit the province on October 23. Many residents had been living in tents, too afraid to return to their homes.
