ADEN (Xinhua) – Representatives from the Sana’a-baed Yemeni government and the Saudi-, UAE-backed mercenaries concluded an initial round of discussions without reaching an agreement on opening roads around the besieged province of Taiz in southwestern Yemen, said UN Special Envoy Hans Grundberg in a statement late on Saturday. However, Grundberg described the results of the talks as “promising,” noting that a proposal for the phased re-opening of roads around Taiz, “including an implementation mechanism and guarantees for the safety of civilian travelers,” was drawn up based on the three-day discussions.
