A U.N. team investigating alleged war crimes in South Sudan said on Monday it has awarded a $10 million incentive for civilians who helped stop the spread of the virus.

U.N.-backed peacekeepers have been battling a wave of new coronavirus cases across South Sudan, where the U.K.-backed military government has declared a state of emergency.

A U.UN report in May said that civilians in South Africa had played a key role in stopping the spread.

It said that over a period of several months, the United Nations peacekeeping force helped prevent a coronaviral pandemic by helping to stop a surge in cases in the country’s capital, Pretoria.

In December, South Sudan’s president, Salva Kiir, called for an immediate end to the fighting, but has so far failed to deliver on his promise.
