South Africa violence: Troop numbers on streets double to 5,000 amid looting - and more could be deployed

The number of soldiers deployed on the streets of South Africa has doubled to 5,000 as the army and police struggle to quell days of looting and violence. President Cyril Ramaphosa is considering boosting troop numbers even more, as at least 72 people have been killed in the worst unrest in the country for years. And some citizens are arming themselves to protect their property and businesses from the rampage, which has hit two of South Africa's nine provinces - KwaZulu-Natal, where Durban is located, and Gauteng, which includes Johannesburg.
