Rescuers in Vietnam were working Saturday to recover the bodies of two brothers buried under huge boulders as a local official said 18 people had died in a quarry rockslide.
"We will keep going until we find their bodies," said Nguyen Tien Loi, chairman of Yen Thanh district people's committee, the local government office, after authorities recovered 16 corpses and gave up hope of finding survivors.
About 200 troops were mobilised to find trapped workers after a massive rock fall on Friday at Len Co quarry in Nghe An province, north central Vietnam.
"We have even used explosives to break the rock, but so far, no luck yet. It is not easy to move rocks weighing hundreds of tonnes," Loi said from the accident site.
Six workers had been rescued from the rocks on Friday, Loi said. Two of them had minor injuries while four others were in a more serious condition.
Deadly accidents frequently occur in quarries in the communist country where labour and safety regulations are often disregarded.
