More than 100 people had been involved in the search for workers at the El Teniente copper mine, the world’s largest underground mine.

All five workers trapped at a copper mine in Chile have been found dead, according to a regional prosecutor, after rescue teams cleared more than 24 metres (78 feet) of underground passages that collapsed in a strong earthquake last week.

Prosecutor Aquiles Cubillo of the O’Higgins region said on Sunday that the body of the fifth trapped worker had been found at the El Teniente copper mine.

More than 100 people had been involved in the search for workers at the El Teniente copper mine, the world’s largest underground mine, in Rancagua, about 100km (62 miles) south of Santiago.

“We deeply regret this outcome,” Cubillos said.
