Turkish media say a seven-storey building has collapsed in the south of the country.
They say the building came down in the southern city of Malatya on Tuesday morning.
There are contradictory reports about possible casualties. CNN-Turk television says the building was under construction and empty, although one person has been injured.
NTV television, however, says there were businesses operating under the building.
The Anatolia news agency says several ambulances rushed to the scene.
