The prosecutor of the International Criminal Court filed genocide charges Monday against Sudan’s president, accusing him of masterminding attempts to wipe out African tribes in Darfur with a campaign of murder, rape and deportation.

Luis Moreno-Ocampo asked a three-judge panel at the International Criminal Court to issue an arrest warrant for President Omar al-Bashir to prevent the slow deaths of some 2.5 million people forced from their homes in Darfur and still under attack from government-backed janjaweed militia.
