It may take two or three more days to free nine miners trapped in an unauthorised copper mine, Peru's prime minister said on Monday as rescuers continued to feed the men through a hose.
The miners have been stuck since Thursday when a shaft collapsed inside the Cabeza de Negro mine.
Rescuers have been able to communicate with the men through a hose and send them liquids.
Prime Minister Oscar Valdes said he had spoken to the miners. He estimated it would take to three days to free the men and said their health appeared to be fine.
Dozens of rescue workers are digging away the 26 feet of collapsed earth and rock blocking the entrance.
Local police chief Jose Saavedra said several tons of earth and rock have already been removed but Mining Minister Jorge Merino appealed for mining companies to provide heavy equipment and experts to speed up the effort.
Foreign Minister Alistair Burt's admission that the Cameron government has "supported" a survey of attitudes to US drone strikes in Pakistan's tribal areas amounts to a tacit admission of British involvement.
