South African police in a pre-dawn raid on Tuesday arrested 40 striking workers who had seized equipment worth millions of dollars at Anglo American's Kumba Iron Ore mine, a spokesman said.
"At about three o'clock (0100 GMT) this morning, we entered the mine premises where the illegal strikers were keeping the mine equipment in their possession. We managed to arrest about 40 of them," Lieutenant Colonel Hendrik Swart, police spokesman for Northern Cape, told AFP.
The plight of South African mine workers has recently come under heightened attention. At the end of August, 34 mine workers were killed. Several strikes have since been staged to demand better working conditions by South African miners.
