At least two miners were killed in an incident at a coal mine in northern Russia, news agencies reported Monday.
ITAR-Tass, citing emergency officials, said a "popping sound" was reported around 9 p.m. (1700 GMT) in the Komsomolskaya mine near Arctic Circle city of Vorkuta, followed by a power outage. RIA-Novosti said a sudden burst of gas was reported.
At least 10 miners were underground at the time of the incident, ITAR-Tass and Interfax reported. Two were confirmed dead according to mine officials, and the fate of eight others was unclear.
Emergency officials could not be immediately reached for comment; no one answered the phone at mine operator OAO Vorkutaugol late Monday.
