The Special Envoy of the United Nations (UN) Secretary General for Yemen, Ismail Ould Cheikh Ahmed, says dialogue is the only practical means of restoring peace in war-torn countries.
Ahmed was speaking in Nouakchott, where he represented UN Secretary-General Ban Ki-moon during the 27th edition of the Arab League Summit.
He cited the situation in Iraq, Palestine, Lebanon, Libya and Sudan and the efforts made by the UN to guarantee stability in the countries.
He said the large numbers of refugees and migrants had created a lot of challenges for Arab states as countries of origin, transit and destination.
The special envoy noted that cooperation between the UN and the Arab League had considerably increased in the last few years.
Ahmed expressed satisfaction with the efforts deployed by members of the Arab League to support diplomacy and mediation led by the UN.
