Mine workers protest outside the Lonmin mine in Rustenburg, northwest of Johannesburg January 23, 2014. South African mines producing half the world's platinum are shut as the country's hardline miners union began a strike for hefty pay hikes their employers say they cannot pay. Members of the Association of Mineworkers and Construction Union (AMCU), the sector's main union, downed tools at Anglo American Platinum, Impala Platinum and Lonmin, the top three producers of the metal used in catalytic converters in cars.

Johannesburg - South African police used rubber bullets and stun grenades to disperse about 3,000 striking miners at an Anglo American Platinum shaft on Tuesday, a police spokesman said.

Two miners were arrested at the demonstration near Rustenburg in South Africa's platinum belt northwest of Johannesburg, said spokesman Thulani Ngubane.

“At 8 o'clock this morning the workers were dispersed,” Ngubane said. - Reuters
