South Africa has begundeployingmore than 20,000 troops to assist police in quelling week-long unrest, as the death toll soared to 117 people in the rioting and looting following the jailing of former President Jacob Zuma, authorities said on Thursday.

In one of the largest deployments of soldiers since the end of white minority rule in 1994, the government said 10,000 soldiers were on the streets by Thursday morning and the South African National Defence Force has also called up all of its reserve force of 12,000 troops.

In a show of force, a convoy of more than a dozen armoured personnel carriers brought soldiers on Thursday into Gauteng province, South Africa’s most populous, which includes the largest city, Johannesburg, and the executive capital, Pretoria.

Buses, trucks, aeroplanes and helicopters were also being used to move the large deployment of troops to trouble spots in Gauteng and KwaZulu-Natal province that have seen a week of violence in mainly poor areas.

The unrest, which began last Friday, was triggered by the jailing of former President Zuma but widened into grievances over inequality and poverty.

More than 2,200 people have been arrested,the acting minister in the presidency, Khumbudzo Ntshavheni,told a news conference, adding that Johannesburg was now “relatively calm”.

But in KwaZulu-Natal province, the epicentre of the violence, the minister said the “situation remains volatile, but much improved and moving towards stability”.

About 100 acts of violence had been recorded on Wednesday, but fewer than three dozen on Thursday, she said.

The violence has so far not spread to South Africa’s seven other provinces, where police are on alert. (Al Jazeera)
