A methane gas explosion caused a mine to collapse in a remote area in southwest Pakistan, trapping at least 12 miners, officials said Friday as authorities launched an operation to rescue the miners.

Indian authorities have summoned the army to help rescue at least nine workers who are trapped inside a flooded coal mine in the country's northeastern Assam state.

The body of one of the nine workers trapped inside a coal mine in Assam's Dima Hasao district was recovered by army divers on Wednesday, the third day of the rescue operations, officials said
