An explosion ripped through a coal mine close to Balikesir in northwest Turkey on Tuesday, Turkish television stations reported, with up to 50 workers believed missing.
Local district governor Ibrahim Kucuk told reporters, "We can't give any information yet about any dead or injured but a large number of people are underground."
The explosion comes two months after 19 workers died when a coal mine close to the city of Bursa collapsed after a dynamite explosion.
Mining disasters are common in Turkey. The worst disaster, at Zonguldak, in 1992 killed 263 workers.
