South African President Cyril Ramaphosa is facing calls to order a national 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.

Illegal mining is common in parts of gold-rich South Africa. Typically, undocumented miners known as zama zamas - from an isiZulu expression for "taking a chance" - move into mines abandoned by commercial miners and seek to extract whatever is left. Some are under the control of violent criminal gangs.

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.
