On Wednesday, the government said it would call out around 25,000 troops to tackle the emergency
The death toll in South Africa's unrest rose to 117 on Thursday as the country called up its army reserves in a bid to quell looting that has stoked fears of shortages and dealt a crippling economic blow.
The acting minister in the presidency, Khumbudzo Ntshavheni, told a news conference that Johannesburg, South Africa's economic capital, was now "relatively calm" while the southeastern province of KwaZulu-Natal (KZN) -- the epicentre of the violence -- "remains volatile."
The defence, security and police ministers and top army generals were dispatched to KZN to assess the situation and oversee the expanded deployment of security forces.
On Wednesday, the government said it would call out around 25,000 troops to tackle the emergency -- 10 times the number that it initially deployed.
"All reserve members are to report for duty at first light tomorrow morning 15 July 2021 at their respective units," army chief Lieutenant-General Lawrence Mbatha said in orders issued overnight as the unrest entered its sixth day.
Minister Ntshavheni said "by this morning, 10,000 boots were already on the ground."
Stores and warehouses in Johannesburg and KZN have been ransacked, devastating supply chains on which food, fuel and medicines depend in Africa's most industrialised economy.
South Africa's consumer goods regulatory body estimates that more than 800 shops have been plundered. At least 2,203 people have been arrested during the unrest.
Looting continued on Thursday in KZN, but the situation was quieter in Johannesburg, where volunteers in the city's townships took part in cleanup operations.
Residents lined up for their turn to buy food and other essentials at a mall in Alexandra township in northern Johannesburg that had been spared looting, as 20 soldiers patrolled the floors.
Volunteers took part in a cleanup operation at the Jabulani shopping centre in Soweto.
Community leader Musa Mbele-Radebe, 30, told AFP: "The use of the army is quite good, because our people are quite scared of the army compared to the police.
"It only took four soldiers to control a situation of a thousand (people) that was gathering in this mall."
The unrest began a day after former president Jacob Zuma -- who commands support from some of the country's poor -- began a 15-month jail term on July 8 for refusing to testify to a commission probing corruption under his tenure.
Protests quickly turned into looting as crowds pillaged shopping malls, hauling away goods as police stood by, seemingly powerless to act.
As the crisis escalated, the armed forces on Monday said they were sending 2,500 troops to help restore order.
The figure was criticised by many as paltry, given that 70,000 soldiers were deployed last year to enforce a strict coronavirus lockdown.
On Wednesday, Defence Minister Nosiviwe Mapisa-Nqakula told parliament she had submitted a request for "plus or minus" 25,000 troops.
The request came after President Cyril Ramaphosa warned that parts of the country "may soon be running short of basic provisions" following disruption to supply chains.
TV footage of the casual looting has deeply shocked many South Africans. Business confidence has been savaged at a time when the economy is already mired in unemployment, especially among young people.
Michael Sun, a safety and security official for the opposition Democratic Alliance, said he went on a tour of Johannesburg and saw a car dealer whose 50 vehicles were just burnt-out shells.
"The devastation is really bad," he said. "Lots of the people are salvaging what they can get. Lots of the smaller businesses don't have insurance -- they are struggling."
Locals have started forming vigilante groups to protect property and infrastructure in their neighbourhoods.
Tensions are high in Durban's Phoenix township between black South Africans and counterparts of Indian heritage where police Minister Bheki Cele said 15 people had been killed in clashes. The hashtag #PhoenixMassacre was trending on Thursday.
"The Indian nation here in KZN is the second largest outside of India," the new Zulu king, Misizulu Zulu, said in an appeal to his community on Wednesday.
"We have lived in peace for many years alongside them. Therefore I ask: Let us be understanding and thoughtful towards each other."
