A blast at a mine in a separatist-controlled part of eastern Ukraine's Luhansk region has killed at least one miner.
Larisa Airapetian, the top health official of the Russia-backed separatist's self-declared government in the Luhansk region, said on May 4 that the gas explosion at the Maloivanivska mine also had trapped nine miners underground.
Airapetian said four other miners were hospitalized with burn injuries from the May 3 gas explosion.
Airapetian said efforts to rescue the nine trapped miners were underway on May 4.
Three districts of Ukraine's Luhansk region have been under separatists' control since April 2014.
