The South African government has launched a rescue operation at an abandoned gold mine in the country’s North West province, where at least 109 men have died, a group representing the miners said, after local authorities cut off vital supplies in a dramatic bid to crack down on the country’s illegal mining trade.

Rescuers recovered 51 additional bodies from an abandoned gold mine in South Africa on Tuesday, raising the death toll to 60 after nine bodies were retrieved on Monday, the first day of a massive rescue operation.

A total of 118 illegal miners, including 36 dead, have been extracted from an abandoned gold mine in South Africa. The operation has led to arrests for illegal mining and trespassing.
