UN Secretary-General Antonio Guterres has called for an immediate ceasefire in and around the El Fasher area in Sudan's North Darfur, his spokesman said.
The UN chief is appalled by the relentless attacks by the Rapid Support Forces on North Darfur's capital, spokesman Stephane Dujarric said in a statement on Friday.
"El Fasher has been under a tightening siege for more than 500 days with hundreds of thousands of civilians trapped in the area," he said.
