The Khartoum North Criminal Court sentenced 18 people to death on Sunday for their part in a 2014 tribal clash.
The court convicted 18 members of El Bzaa tribe, of the intentional killing of seven members of El Shanabla tribe and causing serious harm. The judge sentenced them to death by hanging and then crucifixion.
Those convicted include the Omda of El Bzaa tribe and the deputy head of a rural court.
In 2014 a group of El Shanabla tribesmen were out on search for a missing herder in White Nile state, when a militant group from El Bzaa tribe group ambushed them. Seven were killed and three others injured.
