South African President Cyril Ramaphosa has called for people to “stand against violence” in response to deadly unrest triggered by the jailing of former President Jacob Zuma.
At least six people have been killed and nearly 500 arrested since Zuma handed himself in to police last week.
Shops have been looted and buildings set on fire.
Troops have been deployed in Gauteng province, and in Zuma’s home province of KwaZulu-Natal.
Zuma was convicted of contempt of court after failing to attend an inquiry into corruption during his presidency.
The 79-year-old, who denies corruption, was given a 15-month prison sentence. He is hoping to get the sentence rescinded or reduced by the country’s constitutional Court. However, legal experts say his chances of success are slim.
