The Sudanese town of Abyei has been set on fire, with gunmen looting property, the United Nations says.
The town and surrounding area are claimed by both Khartoum and by South Sudan, set to become independent in July. The town was captured at the weekend by northern troops, BBC online reports Monday.
The UN has urged Sudan’s government in Khartoum to withdraw its forces. Sudanese President Omar al-Bashir later said that Khartoum wanted to resolve the issue peacefully.
South Sudan’s secession (løsrivelse) follows decades of north-south conflict and some fear this dispute could reignite the war.
In a statement, the UN Mission in Sudan (Unmis) said that the northern troops were “responsible for maintaining law and order in the areas they control”, urging Khartoum to “intervene to stop these criminal acts”.
South Sudan earlier denounced the Abyei takeover on Saturday as an act of war. A southern military spokesman told the BBC the north had attacked the area with 5.000 troops, killing civilians and southern soldiers.
Some 20.000 people, almost the whole population of the town, had fled, aid agency Medecins Sans Frontieres (MSF) said.
Khartoum has said it acted after 22 of its men were killed in a southern ambush last Thursday. The northern troops were travelling in a UN convoy. UN officials have described the incident as “a criminal attack” and the US called on South Sudan to “account” for the assault.
Under a 2005 peace agreement, which ended 22 years of civil war, Abyei was granted special status and a joint north-south administration set up in 2008.
