A natural stone quarry in Indonesia’s West Java province collapsed on several people who were working in it, killing at least 10 people and leaving six workers missing, officials say.

A rock collapse at a quarry at Cirebon in West Java province has killed 19 people, injured eight and there are six still missing, local police said on Sunday. Indonesian search and rescue agency Basarnas said authorities continued their search on Sunday for people trapped in the rubble after the collapse on Friday.

Officials halted rescue operations on Friday evening after poor lighting and the possibility of more landslides put rescue workers at risk.
