(KUNA) -- Eight rebels were killed on Monday and 17 were injured in armed clashes within the ranks of the rebellious AL-Khalas National Front movement in the "Jabal Afein" north of Darfur. A source from the Sudan press center quoted the leader of the armed movement Issak Juma'ah saying that the clashes occurred as a result of differences which occurred in the beginning of this month between the commanding officer of the armory forces Othman Haaren and his replacement commander Hamid Juma'ah leader of the north sector.The source added rescue efforts managed to help those who belonged to the movement in one of the villages under their control. Al-Khalas front is a military alliance of movements who refused to sign the Darfur peace agreement last May.
