21 workers killed in Colombian coal mine explosion.

A coal mine in central Colombia collapsed following an explosion that blocked several of its entrances, leaving 21 workers dead. Nine workers survived the accident and had been released from hospital, while the relatives of miners who were killed were receiving psychological support. The explosion was caused by methane inside the mine, and the complex would remain closed until officials investigate how the explosion occurred. Mining accidents are common in Colombia, particularly in coal and gold mines.
