Sudan: The Darfur conundrum

On 31 March 2007, five African Union peacekeepers in Darfur were killed in the most fatal attack on them since the force arrived in the western province of Sudan in 2004. At the time of writing, the spokesman for the African Union (AU) has been unable to say who was responsible for the attack. This is the conundrum in Darfur: the killers could have belonged to any of the several armed groups there, though most reports suggest that one of the rebel forces was likely responsible.
