ADDIS ABABA (Reuters) – Gunmen have killed a UN driver in Ethiopia's Somali Region in an ambush that also injured another staff member, the World Food Program said on Saturday.

The province, also known as Ogaden, is home to a low-key insurgency led by the Ogaden National Liberation Front (ONLF), which has fought for independence since 1984.
""Farhan Hamsa -- a WFP driver -- was killed in an ambush on 13 May by unknown assailants in the Somali Region of Ethiopia,"" the UN agency said in a statement.
""One other WFP staff member was injured in the attack and two remain missing.""
The Horn of Africa nation signed a peace deal with one faction of the group last year, but has acknowledged skirmishes in the region with ""other remnants"" in 2010.
