JOHANNESBURG (AP) — South Africa’s army has begun deploying 25,000 troops to assist police in quelling the weeklong riots and violence sparked by the imprisonment of former President Jacob Zuma. In the largest deployment of soldiers since the end of white minority rule in 1994, the South African National Defence Force has also called up all of its reserve force of 12,000 troops. Trucks, armored personnel carriers and helicopters are being used to transport soldiers to trouble spots in the Gauteng and KwaZulu-Natal provinces that have seen a week of violence in mainly poor areas. The violence erupted last week after Zuma began serving a 15-month sentence for contempt of court.
