Rescuers in Chile are racing to find the last worker trapped in the world's largest underground copper mine after an earthquake on Thursday. The state-owned Codelco company said on Sunday that five workers were now known to have died since the collapse of its El Teniente mine, about 70km (43 miles) south-east of the capital Santiago.

One of the five workers trapped in a Chilean copper mine has been found dead, the mining company said Saturday, bringing the death toll from Thursday’s collapse to two.

Some 100 people were involved in search for workers at El Teniente copper mine, the world’s largest underground mine.
