Ethiopia has deployed five air force Mi-35 helicopters in Nyala, South Darfur, as part of the government's promise to the UN-AU Mission in Darfur (UNAMID).
The Ethiopian Defence Ministry said the Mi-35 helicopters would be used to support the ongoing peacemaking efforts in the troubled region.
The tactical helicopters, with 15 pilots and crew, will join a 185-member advance team, including pilots, technicians and protection forces.
The Mi-35s will be used for troop deployment and monitoring the security situation in Darfur.
UNAMID was formally established by the Security Council on 31 July 2007, under Chapter VII of the UN Charter.
