Police say several people have been shot and injured as miners from rival unions clashed at an Anglo American Platinum mine in South Africa.

Spokesman Brig. Thulani Ngubane said he did not know how many people were shot or injured by sharp objects or if anyone died in the Monday confrontation. He said those involved were members of the National Union of Mineworkers, an upstart challenger Association of Mineworkers and Construction Union as well as mine security guards.

No immediate comment was available from the world's largest platinum producer.

Rivalry between the two unions led to violent and prolonged strikes last year that killed scores of people at a Lonmin platinum mine, culminating in the police shooting of 34 strikers that shocked the nation.
