Two Egyptian peacekeepers Friday have been killed by gunmen in Sudan's Darfur region, the joint United Nations-African Union mission (Unamid) says. It says three other Egyptian soldiers were injured in an ambush near Edd al-Fursan, South Darfur. They were later airlifted to a Unamid hospital. No group has so far claimed responsibility for the attack. More than 20 peacekeepers have been killed since Unamid was deployed in Darfur in 2008. A civil war has pushed about three million people into refugee camps in Darfur and the region is prone to lawlessness and banditry.
