A coal mine exploded in Indonesia’s West Sumatra province on Tuesday, killing five people and trapped at least 30 others underground, according to the latest information of the local Disaster Management Agency. Ade Edward, an official with the agency, said 10 other people were seriously injured in the explosion which happened early Tuesday morning in Sawah Lunto. Despite the efforts, the trapped people have not been able to be taken out of the one-meter-wide exit. They have slim chance of surviving as there is no oxygen supply equipment Edward said.
