Khartoum (AFP) - Heavy fighting in Sudan's west and south has killed at least 27 people and left dozens wounded, residents said Tuesday, with the United Nations envoy saying he was "deeply concerned."
In separate incidents, clashes broke out in the restive Darfur region in a bitter land dispute, leaving 16 dead, as well as in South Kordofan state, where 11 people died after an argument between two people reportedly escalated into wider gun battles.
The latest violence comes as Sudan grapples with the fallout from a coup in October last year led by army chief Abdel Fattah al-Burhan.
In West Darfur, the arid region of Sudan bordering Chad, fighting took place near Kolbus, some 160 kilometres (100 miles) from the state capital El Geneina.Attackers set fire to villages leaving them burned to the ground.
It is the latest in several rounds of clashes pitting largely settled farmers against semi-nomadic Arab pastoralist groups.
"Fighting erupted over a land dispute between member of an Arab tribe and a farmer from a non-Arab one," said a leader from the non-Arab Gimir people."The clashes killed eight people from Gimir, and three villages were burned."
A leader from the Arab Rizeigat community said fighting began over a dispute over land.
"Eight of our people were killed," he said."Clashes are ongoing."
In South Kordofan, fighting erupted between rival Arab groups -- the Hawazma and Kenana groups -- near Abu Jebeiha.
"At least 11 people were killed and 35 wounded in fighting," said one resident, who is involved in mediation efforts between the rivals.
He said fighting began as a dispute between two people, but spread into clashes between the groups.
"I am deeply concerned about inter-communal clashes," UN special representative Volker Perthes said Tuesday, over the fighting in South Kordofan.
"I call on security forces to secure the area and ensure the protection of civilians, and urge local leaders to undertake mediation efforts".
Both Darfur and South Kordofan suffered heavily during decades of civil war during the three-decade rule of president Omar al-Bashir, who armed some Arab groups to fight ethnic minority rebels demanding an end to marginalisation by his Arab-dominated regime.
The scorched-earth campaign left 300,000 people dead and displaced 2.5 million, according to the United Nations.
While key rebel groups signed a 2020 peace deal, deadly clashes still erupt over land, livestock, access to water and grazing.
The regions remain awash with weapons, and have seen a renewed spike in deadly violence in recent months, fanned in some areas by intense droughts and creeping desertification.
In April, more than 200 people were killed in clashes between Arab and non-Arab groups in West Darfur.
