Two separate accidents at mines in Ukraine have claimed the lives of 37 miners, Reuters reported Sunday:
Rescue work ended on Sunday at two Ukrainian coal mines where accidents killed 37, and the former Soviet republic held a national day of mourning.
An explosion in a mine in the Luhansk region early on Friday killed at least 26 people and injured two, according to an updated report on the Emergencies Ministry website.
Also early on Friday, 11 miners died and four were injured at a state-owned mine in the neighbouring Donetsk region when a piece of heavy machinery collapsed.
The news service said the Luhansk disaster was the deadliest in a Ukraininan coal mine since 2007. The cause of the explosion has not been established, though methane is suspected.
