Secretary-General Antonio Guterres hailed "tangible progress" made in recent months in tackling Libya's almost decade-long crisis, in a report submitted Monday to the Security Council in which he demanded all foreign troops and mercenaries leave the country by the week's end. "Tangible progress was achieved in advancing the UNSMIL-facilitated political, security and economic intra-Libyan dialogues over the last few months," said the document, obtained by AFP and referring to the U.N. mission in Libya. Guterres said that "sustained international engagement" in U.N.-facilitated talks "has generated considerable impetus, demonstrated by tangible progress on the political, security, economic and international humanitarian law and human rights tracks, moving Libya forward on the road to peace, stability and development."
