Listvyazhnaya mine disaster

The Listvyazhnaya mine disaster was a mining accident that happened on 25 November 2021 in a coal mine in Kemerovo Oblast, Russia. Smoke from a fire in a ventilation shaft caused the suffocation of over 40 miners. 
A rescue gone wrong trapped miners and caused the deaths of at least five rescuers when the mine exploded. It is the deadliest mine accident in Russia since the 2010 Raspadskaya mine explosion in the same region.
