The International Criminal Court has opened another war crimes probe after three months of war between feuding generals. 87 bodies were buried in a mass grave by the Rapid Support Forces (RSF) paramilitary group prompting a UN warning of possible new massacres in Darfur. The ICC has been investigating crimes in Sudan's Darfur region since 2005. The UN Security Council charged former leader Omar al-Bashir with genocide and crimes against humanity - murder, rape and torture. Allegations of similar atrocities have mounted during recent fighting. UN officials are calling for the warring sides to face accountability. About 3,000 people have been killed and three million displaced since violence erupted between Sudan’s army chief Abdel Fattah al-Burhan and his former deputy Mohamed Hamdan Daglos. The UN warns history could repeat itself - the people of Darfur have lived with uncertainty, pain and the scars of conflict for almost two decades.
