Karim Khan, the prosecutor at the International Criminal Court (ICC), has told the BBC that “there is no hope of peace in Sudan without some type of justice”.
Speaking to Focus on Africa from the UN in New York, Mr Khan said “new generations of Darfurians are being inflicted with new violence that is no fault of their own”.
It follows the news yesterday that the bodies of 87 people, allegedly killed by the Rapid Support Forces (RSF), were found in a mass grave in Darfur.
On Thursday, he announced that his office is looking atrecent atrocities in the Darfur region, as part of an on-going investigation.
The ICC have been investigating events there since 2005, after being referred by the UN Security Council.
He also said that he has seen no willingness from either side of the conflict to hand over former dictator Omar al-Bashir, who ruled the country for three decades.
Al-Bashir is wanted by the ICC for alleged genocide committed in Darfur during the first conflict.
Mr Khan said his office is launching a public appeal for those who have evidence of war crimes in Sudan to come forward.
