UN sounds alarm after dozens killed

The UN yesterday expressed deep concern over the latest deadly tribal violence in Sudan's Darfur region, which has hampered assistance for tens of thousands of people forced to flee earlier fighting.
Residents in the North Darfur town of El Sireaf said an Arab militia firing heavy machine guns and rocket-propelled grenades burned houses and killed more than 50 people on Saturday.
Official media reported a toll of 60.
"We are deeply concerned by the violence," Damian Rance of the United Nations Office for the Coordination of Humanitarian Affairs (OCHA) told AFP.
"It's affected our ability to run a humanitarian operation."
