President Cyril Ramaphosa addresses unrest in response to jailing of Jacob Zuma

South African president Cyril Ramaphosa has said the deadly violence gripping the country is unprecedented post-apartheid as he deployed troops to help police crush the violence and looting prompted by the jailing of ex-president Jacob Zuma.

Ten people have died, some with gunshot wounds sustained before the army was deployed, and 489 people have been arrested. Among those killed was a 15-year-old boy who was shot in the chest with a rubber bullet, local media reported.
