Rebels in Donetsk said an electricity sub-station was damaged in shelling, cutting power to the Zasyadko coal mine in Donetsk. The mine is notorious for its safety standards; 33 people were killed there in 2015 by a methane blast.
With elevators not working, the miners had been trapped underground for several hours before local authorities found the backup generators outside the mine to get the elevators working. By midday today, at least 152 of 200 men had been able to get out.
The artillery shelling, which appears to be the worst in many months, was concentrated around the government-controlled town of Avdiivka, home to a giant coking plant.
Its director said yesterday that preparations were being made to stop production, something rarely done throughout the conflict that has claimed more than 9,600 lives since it began in 2014. A cease-fire deal struck in Minsk in 2015 has helped to reduce but not stop the fighting.
The press office of the Ukrainian government's operation in the east reported an unspecified number of civilian casualties. It also said the rebels turned down the government's offer to cease fire to allow the removal of the dead and wounded.
In Donetsk, the rebels' Donetsk News Agency reported four rebel fighters died and seven were injured overnight as well as three civilians. One civilian was killed in shelling in Donetsk, Basurin told Russian news agencies.
