A coal mine explosion believed to be caused by a transformer in Turkey's northern Bartin province left 49 workers trapped on Friday, Governor Nurtac Arslan was quoted as saying.
"Right now, there are 44 people 300 (meters below the entrance of the mine) and five people 350 (meters below)," Arslan was quoted as saying by state-owned Anadolu Agency.
Eight people were able to leave the mine by their own means, Arslan said.
