ZHENGZHOU, Sept. 21 (Xinhua) -- A gas outburst at a coal mine in central China's Henan Province early on Sunday has killed 37 people, rescue official have confirmed.

    The accident happened at about 1:10 a.m. at Xinfeng No. 2 Coal Mine, southwest of Dengfeng City, when 108 workers were underground.

    The spokesman said 64 escaped and seven injured, who were taken out of the pit safely, were being treated in hospital.
