Police say the death toll in a monthslong standoff between authorities and miners trapped while working illegally underground at an abandoned gold mine in South Africa has risen to at least 87.

The clampdown on illegal mining cut off food and water to hundreds of miners underground. At least 78 bodies were pulled from a mining shaft this week, and more are believed to remain underground.

South African rescuers have pulled out 36 dead bodies and 82 survivors from a gold mine deep underground in two days of operations, police said on Tuesday, adding that the survivors would all face illegal mining and immigration charges.
