More than 100 people have been killed over several days of fighting between rival groups of an Arab tribe in Sudan’s West Kordofan state.
A tribal leader said the Awlad Omran and al-Ziyoud of the Messiriya tribe began with a land dispute.
The Messiriya are one of the largest tribes in Kordofan, which is the main oil-producing region in Sudan.
The Sudanese government armed the clan during the country’s 22-year civil war which ended in 2005.
