Security is beefed up at South Africa's Lonmin mine after nine people were killed in clashes between labor unions.

Police told Reuters two policemen died after a machete attack by a mob near the mine.

It was the deadliest violence to date in a union turf war between South Africa's dominant National Union of Mineworkers .... and the relatively new Association of Mineworkers and Construction Union.

"We say to workers, everyone must go back to work, but the situation as it is, how would you go to work? "

On Tuesday another dead body was found near the platinum mine although the cause of his death is still unknown.

South Africa is home to 80 percent of known platinum reserves.
