Rescue teams are continuing the search for two workers who went missing after a gas explosion at the Liushenyu Coal Mine in Changzhi City, north China's Shanxi Province. Authorities said the accident, which happened at 7:29 p.m. on Friday, had killed 82 people and injured 128 others as of late Saturday. A mine inspection robot equipped with gas sensors and a live camera feed was sent underground early Sunday to expand the search in areas difficult for rescuers to reach.
