Nigerian President Muhammadu Buhari said that as long as Libya remains unstable, the proliferation of weapons and problems in the African Sahel region will continue.

This came in Buhari's talks with South Sudanese President Salva Kiir Mayardit, at a bilateral meeting in Ethiopia on Thursday.

In this regard, he referred to the turbulent situation in several African countries such as Guinea and Mali, calling on African leaders to support efforts directed towards the return of democracy in the two countries.

Nigeria and Cameroon are witnessing a steady escalation in the pace of terrorist acts with the expansion of terrorist groups such as Boko Haram, ISIS and Ansar al-Din. In Mali, the Tuareg rebellion and militants who experienced the war in Libya helped to sweep northern Mali in 2012, equipped with an arsenal, while the Chadian army faces rebels in the north of the country, where former President Idriss Deby was killed last April while inspecting his forces.

Libya, along with Niger and Sudan, suggested reviving a Quartet Agreement by forming a joint military force to prevent the incursion of terrorist and rebel groups.
