Ukraine gas blast 'kills 30' at Zasyadko coal mine

A suspected gas blast at a coal mine in a rebel-held region of east Ukraine is believed to have killed some 30 miners, the rebels told the BBC.

One is confirmed dead and 14 were injured at the Zasyadko mine, which saw Ukraine's worst mine disaster nearly eight years ago when 101 were killed.

Anxious relatives of miners have gathered at the scene to await news.
