KHARTOUM, May 7, 2012 (AFP) - Four children were killed and one was wounded when leftover munitions exploded in Sudan's Darfur region, the African Union-United Nations peacekeeping mission (UNAMID) told AFP on Monday.

A UNAMID spokesman said the incident occurred when a UXO (unexploded ordnance) detonated in Tringlat, north of the West Darfur state capital El Geneina.

The UN estimates that at least 300,000 people have died as a result of the Darfur conflict, which began in 2003 when rebels from non-Arab tribes in Sudan's far west rose up against the Arab-dominated Khartoum regime.

The Sudanese government puts the death toll at 10,000.

Elsewhere in Sudan, the UN's humanitarian agency OCHA said last month it had received reports that three children died in Kadugli, the capital of South Kordofan state, when they found a UXO which then detonated.

Government troops have been battling rebels in South Kordofan since last June.
