Unidentified gunmen attacked a UN patrol in Sudan's Darfur region on Friday, killing one UN peacekeeper and injuring another in the second such incident this week, the UN said according to dpa. The UN said the gunmen fired at a UN vehicle in Nyala in South Darfur, killing the peacekeeper who belonged to the joint UN-African Union Mission in Darfur (UNAMID). "UNAMID personnel have been sent to assess the scene of the incident," the UN said. "Government police are also searching the area and the vehicle has been recovered." The UN said the attack was a "deplorable act" and it was working with the Sudanese police to find the perpetrators and bring them to justice.
