Ten workers have been killed in an explosion at a coal mine in the east of Indonesia, an emergency services official said on Friday.
The miners were in a legally operated coal mine in the province of West Sumatra.
The explosion was caused by methane, according to a press release from the emergency services, adding that the bodies of ten miners had been found, and that four people had been rescued.
Mining accidents are common in this mineral-rich Southeast Asian archipelago.
In September, at least seven people died in a landslide-hit mine on the island of Borneo. In April, twelve miners from an illegal gold mine in the province of Sumatra were killed in a landslide.
