Nearly 200 workers were caught in a series of explosions at a fireworks factory in northwestern Turkey, which left at least two dead.
Local governor Cetin Oktay Kaldirim said many were trapped by the blasts and emergency services were unable to reach the building.
President Recep Tayyip Erdogan gave details of the deaths and said 74 others were injured.
The explosions in Hendek could be heard from dozens of kilometers away.
A black cloud of smoke rose over the factory and the government's disaster agency described the explosions as an industrial accident.
Erdogan said 189 people were working on the scene at the time of the blasts.
Local mayor Turgut Babaoglu said that many of them managed to escape the blasts, which started around 11:15 am (08:15 GMT).
Babaoglu said dozens of firefighters and rescue workers had been dispatched to the scene.
