South Africa's president is facing calls to order an inquiry into a police operation that was meant to combat illegal mining but ended up leaving 87 miners to die underground as authorities attempted to force them to surrender during a monthslong standoff.

By Siyabonga Sishi and Nellie Peyton STILFONTEIN, South Africa (Reuters) - South African rescuers were making final efforts on Thursday to ascertain whether anyone was left in an illegal gold mine deep underground where at least 78 people died during a police siege,

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.

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.

Hundreds are still trapped at the Stilfontein gold mine, a rights group said. Authorities tried to flush out the miners by depriving them of food and water.

At least 78 dead bodies have been pulled from an illegal gold mine in South Africa where police cut off food and water supplies for months, in what trade unions called a "horrific" crackdown on desperate people trying to eke out a living.

South African authorities have come under intense scrutiny for their response after civic groups said hundreds of miners have been trapped deep in an abandoned gold mine for months.

Rescue teams in South Africa have stepped up efforts to pull out survivors and the corpses of illegal miners trapped underground for about two months, following one of the most extraordinary tragedies to hit the industry.

Rescuers and volunteers have pulled at least 78 dead miners and more than 160 survivors from an abandoned South African gold mine.
