In May 2008, the Justice and Equality Movement (JEM), a Darfur ethnic minority rebel group, undertook a raid against the Sudanese government in the cities of Omdurman and Khartoum. From the government's viewpoint, the attack took place on a single day, May 10, 2008, while JEM has countered the government's account with reports of heavy fighting in parts of the Khartoum metropolitan area into May 11. More than 220 people were reported to be killed in the raid, including a Russian pilot, and scores were later sentenced to death.
