The explosion at the Krasnolimanskaya mine in the Donetsk Region occurred when 396 miners were working the night shift.

"The body of the miner was discovered at 00:35 (21:35 GMT) and was bought to the surface at 4:40 a.m. (00:40 GMT). Two people are still missing, their fate is unknown," a spokesman said.

Four miners died instantly and three injured workers managed to make their own way out. Three miners are still in hospital, and one of them is in a serious condition. The bodies of four other miners were found last week.

The Krasnolimanskaya mine is known for its poor safety record and is considered high-risk for methane explosions. Last December alone, two fires occurred in the mine.
