At least 37 innocent people have been killed and 18 taken away in new attacks in a place that South Sudan and Sudan both say belongs to them.
This is the most recent fight in a series of battles that have been happening for three years in the oil-rich area of Abyei.
Most of the people who died in the weekend attack were women and children, according to the temporary government in the area.
Markets and homes were set on fire and 1,000 cows were stolen.
Two groups of young people from Warrap State in South Sudan were accused of raiding the area on Saturday and Sunday. They carried out coordinated attacks on four villages in Abyei.
Bulis Koch Aguar, who is in charge of information, culture, youth, and sports in Abyei, criticized the attacks and asked the government in Juba to help resolve the conflict between the Ngok Dinka of Abyei and the Twic Dinka of Warrap.
Last week, a violent attack by two groups of young people with weapons from Warrap State took place in Abyei. At least 53 people, including two UN peacekeepers, were killed in the most deadly incident in the area that is in dispute.
Abyei is still a disputed area between Sudan and South Sudan because they have not agreed on its final status.
More update on this story soon.
