Firebrand politician Julius Malema has been barred by police from addressing striking workers at South Africa's Marikana mine.

Some 2,000 miners had gathered at a stadium near the mine, about 60 miles (100km) north-west of Johannesburg.

Strikes have already halted production at several gold and platinum mines in the resource-rich country.

South African President Jacob Zuma said that the disruption had cost the industry $548m (£337m) in lost output.
