S Africa plagued by mining crisis

Miners gunned down by police, wildcat strikes as workers demand better treatment, and unions fighting sometimes violent turf wars.

It's one of the world's most lucrative, with gold, platinum and diamonds among the minerals that bring in some $12bn annually.

We also talk to Patrick Craven, the spokesman for South Africa's top trade union body in Johannesburg.
