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.

One hundred and eighteen illegal miners have been extracted from the Stilfontein mine in South Africa on Monday and Tuesday as part of a rescue operation, of which 36 were certified as dead, police said in a statement on Tuesday.

South African police lowered a camera down more than a mile (1.5 km) underground into an illegal gold mine on Thursday to ascertain if any survivors or corpses were still there after a months-long siege by authorities in which at least 78 miners died.
