Officials say that armed groups have killed more than 140 people in the town of Jekow in the Gambella region near the western border with South Sudan. The attackers who are said to have been from South Sudan are reported to be members of the Murle tribe. They crossed into Ethiopia and simultaneously attacked about 10 different villages said to be inhabited by the Nuer ethnic group. A number of children were also abducted and taken into South Sudan. The Ethiopian government says that about 60 of the attackers were killed by the defence forces. The Gambella region hosts thousands of South Sudanese refugees who fled after war broke in their country in December 2013.
