More than 70 people have reportedly died while trapped in a mine after a monthlong standoff with the South African government over illegal mining. CBS News' Chris Livesay has more.

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.
