The Ukrainian president has declared a day of national mourning as the death toll from a gas blast in a coal mine reached 32, with one man still missing.
Petro Poroshenko decreed a minute's silence to be observed at midday (10:00 GMT) for the miners killed at the Zasyadko mine in Donetsk region.
The mine is in rebel territory and a demand by Mr Poroshenko to let in government rescuers was rejected.
Fierce battles raged nearby before last month's ceasefire.
The emergencies ministry of the self-proclaimed Donetsk People's Republic told Russian news agencies on Thursday that the bodies of eight more miners had been brought to the surface.
One worker remained missing, it added.
Zasyadko was the scene of Ukraine's worst mine disaster nearly eight years ago, when 101 people were killed.
