United Nations officials say gunmen have fired on Pakistani peacekeepers in the Darfur area of Sudan. Seven peacekeepers were injured. Officials say unidentified attackers opened fire on a group of peacekeepers near Nyala in South Darfur state. Earlier Tuesday, peacekeepers in Darfur said new fighting has killed many people over the past few days. The joint United Nations-African Union delegation in Darfur or UNAMID said the conflict has caused more than fourteen thousand people to flee their homes. The clashes are taking place in the Jebel Marra area of South Darfur and at Jebel Moon in West Darfur. UNAMID did not say who was involved in the clashes. Rebel groups report being attacked by Sudanese government forces.
