Police in South Africa have fired tear gas and rubber bullets to break up a group of striking miners who are refusing to return to work until their pay demands are met.

The miners are among 12,000 workers that Anglo American Platinum fired earlier this month after they staged a wildcat strike at its Rustenburg mine.

Police also said Tuesday that a power station at the site had been set on fire.

Anglo American Platinum has offered to reinstate the miners if they return to work by Tuesday. As part of the deal, the company is also offering a one-time payment of about $230. But the miners say that is not enough, and are demanding a raise like the one Lonmin gave its platinum miners after they went on strike earlier this year.
