At least eight miners have been killed and 20 others are unaccounted for after a methane explosion in a coal mine in western Ukraine.
Emergency officials said 34 miners were working in the area of the blast, about 500m underground. Six injured were brought to the surface.
The incident took place at 12:46 local time (10:46 GMT) at the mine in the Sokal district of Lviv region.
Rescuers are working to free the trapped miners, whose fate is unknown.
There were 172 miners working at the pit at the time.
Ukraine has frequent mining accidents, though this was the first in 2017.
Most of the country's coal is in the Donbass region in the east, in an area currently ravaged by conflict with Russian-backed rebels.
