Darfur governor and former rebel leader Minni Arko Minnawi renewed his call for civilians in the region to take up arms to defend themselves, saying the “current situation necessitates that”, Al Arabiya reported.
He said this administration was leading efforts to stop the fighting between the Rapid Support Forces (RSF) and the army, particularly in Darfur. The conflict is now in its fourth month.
Mr Minnawi has made similar remarks in the past, raising fears that Darfur, which is divided into five states, could descend into an all-out civil war amid growing ethnic tensions.
Elsewhere in the country, fierce fighting was reported between the army and the RSF in Khartoum, Omdurman and Bahri, the three cities that make up Sudan’s capital.
Eyewitnesses in Khartoum said the army carried out the "heaviest" airstrikes so far against RSF positions in several areas. The army said it killed 18 RSF fighters in clashes in Omdurman and Khartoum.
Renewed clashes were also reported in Nyala, the capital of South Darfur state, after a lull in fighting.
The fighting has persisted despite continuing indirect talks between the army and RSF representatives in the Saudi city of Jeddah.
