Several workers may have been injured or killed Sunday in an explosion at a coal mine in southwestern Pakistan's Baluchistan province. This was reported by local media.
Workers were working inside a mine in the Marwara area in the provincial capital of Quetta when an explosion occurred due to the accumulation of toxic gas inside the mine, reports said.
Rescue operations to extract miners from the underground trap continue.
Coal mines in Baluchistan province are notorious for accidental explosions that have killed many people.
