We currently assess that a no-fly zone would restrict essential humanitarian operations and be a major logistical challenge due to the size of Darfur and the lack of available air assets. The African Union-UN Mission in Darfur (UNAMID) is mandated to monitor military activity, including flights prohibited by UN Security Council Resolution 1591. To this end, we continue to press all parties for rapid, full deployment of UNAMID, and work with the UN and any potential donors to ensure UNAMID receives the equipment it so urgently requires.
