Crowds have looted shops and offices in South Africa, defying government calls to end a week of violence that has killed more than 70 people and wrecked hundreds of businesses.
The unrest, the worst in South Africa for years, has also disrupted hospitals struggling to cope with a third wave of COVID-19 and forced the closure of a refinery.
Protests triggered by the jailing of ex-president Jacob Zuma for failing to appear at a corruption inquiry last week have widened into looting and an outpouring of general anger over the hardship and inequality that persist 27 years after the end of apartheid.
Shopping malls and warehouses have been ransacked or set ablaze in several cities, mostly in Zuma's home in KwaZulu-Natal province, and the financial and economic centre Johannesburg and surrounding Gauteng province..
Overnight it spread to two other provinces - Mpumalanga, just east of Gauteng, and Northern Cape, police said.
A Reuters photographer saw several shops being looted in the town of Hammersdale, Kwazulu-Natal, on Wednesday. Local TV stations, meanwhile, showed more looting of shops in South Africa's largest township Soweto, and in the Indian Ocean port city of Durban.
Soldiers have been sent onto the streets to help outnumbered police contain the unrest and order was being restored in some places on Wednesday, such as the northern Johannesburg township of Alexandra, local TV reported.
The National Hospital Network (NHN), representing 241 public hospitals already under strain from Africa's worst COVID-19 epidemic, said it was running out of oxygen and drugs, most of which are imported through Durban, as well as food.
As authorities in Durban seemed powerless to stop looting, vigilantes armed with guns, many of them from South Africa's white minority, blocked off streets to prevent further looting, Reuters TV footage showed. One man shouted "go home and protect your homes".
Other residents gathered outside supermarkets waiting for them to open so they could stock up on essentials.
The poverty and inequality fuelling the unrest has been compounded by severe social and economic restrictions aimed at curbing COVID-19. The United Nations in South Africa expressed concern that disruptions to transport for workers from the riots would exacerbate joblessness, poverty and inequality.
South Africa's largest refinery SAPREF in Durban has been temporarily shut down, an industry official said on Wednesday.
Zuma, 79, was sentenced last month for defying a court order to give evidence at an inquiry investigating high-level looting during his nine years in office until 2018.
He also faces trial in a separate case on charges including corruption, fraud, racketeering and money laundering. The former president pleaded not guilty in court in May. His foundation said on Tuesday that violence would continue until his release.
The national prosecuting authority has said it will punish those caught looting or destroying property, a threat that so far has done little to deter them. Security forces say they have arrested more than 1200 people.
