BEIJING (AP) - More than 40 coal miners are trapped underground by a gas leak in southwest China less than a week after dozens of miners were pulled out safely from a cave-in at another Chinese coal mine.
The official Xinhua (shihn-wah) News Agency says the accident at the coal mine in Yunnan province occurred at about 6:30 a.m. (2230 GMT, Wednesday).
Xinhua cites the provincial emergency response office as saying that a rescue operation is under way.
The report says the exact number of miners underground is still being verified.
China's coal mines are the deadliest in the world, although the industry's safety record has improved in recent years. Last week, 52 miners were rescued from a mine in Henan province.
