The UN mission in Libya on Friday voiced concern over ongoing armed clashes in the capital Tripoli, calling for an "immediate cessation of hostilities".

In a written statement, the UN Support Mission in Libya (UNSMIL) expressed "grave concern about ongoing armed clashes, including the alleged use of indirect fire, in Salaheddine, a densely populated neighbourhood in Tripoli."

It reminded all involved parties of their obligations under international humanitarian law to ensure that civilians and civilian infrastructure are protected.

The UN mission urged "the immediate cessation of hostilities" and called on all parties to "exercise maximum restraint."

It also asked relevant authorities to oversee their units and "bring all the arms under the control of the state" according to UN Security Council resolutions.

According to local sources, two influential military units of the Libyan army have had disagreements recently which have later turned into armed conflicts in Tripoli.
