US Ambassador to Yemen Matthew Tueller welcomed on Saturday calls for reaching a peaceful resolution to the country’s conflict, while voicing concern over the fighting in the capital Sana’a. He told Asharq Al-Awsat that Washington was very concerned with the reports on the unrest in Sana’a and the possibility of the fall of civilian casualties. He therefore urged calm and welcomed the calls for a peaceful resolution. Fighting as been raging in Sana’a between once allies the Houthi militias and supporters of former President Ali Abdullah Saleh. The violence in the capital and the desperate humanitarian situation confirm the need for an immediate halt in fighting and for all sides to make concessions to end the war, added Tueller. In wake of the clashes in Sana’a, Saleh announced on Saturday his readiness to open a new chapter of ties with the Saudi-led Arab coalition to restore legitimacy in Yemen, thereby ending his alliance with the Houthis. He said in a televised address that Yemen has had enough violence, calling on all the people to defend the revolt against forces that have for three years wreaked havoc in the country. He also called on the armed forces to ignore the commands of the Houthis militias.
