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.

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.

It will be a "mammoth task" to identify the bodies brought up from a disused mineshaft in South Africa this week, a police spokesperson says.

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.

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,

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.

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.

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.
