Police water cannons disperse rioters in Johannesburg

Police said on Sunday they used water cannon and stun grenades to disperse rioters in South Africa's platinum belt, after the country's sports minister was attacked by rock-throwing protesters while campaigning for the May 7 election.

Police spokesman said a community hall, municipal centre and the house of a councillor for the ruling ANC were burnt down.

Local media and union leaders said the minister had been attacked by members of the striking AMCU miners' union.
