An explosion at a fireworks factory in northwestern Turkey on Friday killed four people and injured 97 others, officials said.
At least three people were reported missing, according to The Associated Press.
There were 186 workers at the factory outside the town of Hendek, in Sakarya province, Health Minister Fahrettin Koca told reporters.
Koca, who traveled to the area along with two other ministers, said the explosion killed four workers while 97 others were hospitalized. Close to 40 of the injured were later discharged, he said, adding that of the remaining workers, just one was in critical condition.
At least three people remain unaccounted for, Interior Minister Süleyman Soylu told reporters, without saying whether they were feared dead.
The cause of the blast at the factory, which is away from residential areas, was under investigation.
Two helicopters and a plane were sent to the area to assist firefighting teams, whose efforts were hampered by continuing explosions. The blaze was brought under control several hours later, officials said.
Koca said 85 ambulances, two air ambulances and 11 rescue teams were sent to the area.
Earlier, television video showed a large, mushroom-shaped cloud of smoke rising from the factory.
HaberTürk television said authorities blocked roads leading to the factory. Families rushed to the site for news of their loved ones.
