A man was killed in a police shooting during protests over the cost of electricity in a South African township on Monday, the police watchdog said.
Residents angry at the high cost of basic services barricaded roads with burning tyres and set ablaze a municipal building in Thembisa township east of the financial hub Johannesburg.
"We have registered a case of shooting... by a member of the police, and our investigators are on the scene," Independent Police Investigative Directorate (IPID) spokeswoman Lizzy Suping said.
Protests over poor services occur regularly in South Africa, which is battling some of the highest unemployment and crime rates in the world.
The latest bout of protests came after former president Thabo Mbeki warned the country could see an uprising.
Mbeki last month accused his successor Cyril Ramaphosa of failing to deliver on his promises to tackle widespread poverty, inequality and unemployment, which stands at over 34.5 per cent, with youth joblessness at nearly 64 per cent.
A year ago South Africa saw an outbreak of the worst violence the country has experienced since the end of the apartheid era three decades ago. The large-scale rioting and looting left more than 350 dead.
