The death toll of violence in Darfur in western Sudan has risen to more than 125, and 50,000 others displaced, according to a UN statement on Tuesday.
The clashes began on June 6 between the African Gimir and the Arab Rizeigat tribes in Kulbus, 160 km northeast of El Geneina, the capital of West Darfur State.
The UN Office for Humanitarian Affairs in Sudan said in a report that more than 125 were killed and many injured in the clashes, and 25 Gimir villages were burned and looted.
The office added that the clashes also caused about 50,000 people to flee their villages.
One of the leaders of the Gimir tribe, Ibrahim Hashem, confirmed that the situation in all the villages of Kulbus is tense.
"The gunmen are spread around the Gimir villages everywhere and the situation is tense," Hashem said.
He confirmed that the clashes were caused by the dispute over land ownership, saying: "My conviction is that this fighting, which is taking place on a very large scale, is aimed at removing the moon from their lands."
One of the leaders of the Rizeigat tribe refused to speak on the matter.
The representative of the Secretary-General of the United Nations in Sudan, Volker Perthes, condemned the violence in Darfur.
