The United Nations Support Mission in Libya (UNSMIL) announced Thursday that it had established a mechanism for a joint disengagement deconfliction force in the capital Tripoli. In a statement, UN mission said it held a technical military meeting attended by a military commanders in western Libya and agreed on the “establishment of a joint disengagement and deconfliction force” aimed at “consolidating the ceasefire and bringing a sense of normalcy to conflict areas in Tripoli.” The brief statement did not elaborate on the formation of the force, but said that an agreement had been reached on its objectives, tasks and structure. Tripoli had witnessed fierce clashes between rival militias in recent weeks. A ceasefire was reached on September 9. Separately and in a surprise move, the parliament approved the constitutional referendum law during an extraordinary session and amid wide objections. Parliament spokesman Abdullah Blehiq said the MPs agreed that the referendum would see Libya divided into three electoral districts instead of one. Soon after the announcement, lawmakers from the eastern Barqah region announced their rejection of the referendum law, deeming it null and void. In a statement on Friday, they said that Thursday’s parliamentary session was only attended by 30 MPs from the Tripoli region. They said that law violates the constitutional declaration, warning that the development will have “dangerous repercussions on Libya’s unity and coexistence among its people.” They also described the passing of the law as a “clear provocation of the Barqah region and army command.” They demanded in this regard Speaker Aguila Saleh, of the Tobruk-based parliament, to launch an investigations to uncover all the figures “who had deliberately committed all of these legal and constitutional violations.”
