KHARTOUM - Sudanese authorities have arrested suspects in an attack that killed four UN peacekeepers last week in the strife-torn western Darfur region, state media said on Tuesday.
UNAMID, the world's largest peacekeeping mission, was deployed by the United Nations and the African Union in the arid western territory after fierce fighting in 2003 which forced hundreds of thousands of people to flee their homes.
Last week, unidentified gunmen ambushed Nigerian peacekeepers near the western town of El Geneina, killing four soldiers and wounding eight, according to UNAMID.
"Suspects involved in the killing of (U.N.) soldiers have been detained," Sudanese government radio said in a text message sent to mobile phones. It gave no further details.
A total of 42 peacekeepers have been killed since UNAMID was set up, according to the force.
