President Abd Rabbuh Mansour Hadi held talks on Tuesday with UN envoy to Yemen Martin Griffiths in Aden on humanitarian affairs and the release of detainees, Yemeni official sources said. “We held a fruitful session with the president and we focused on humanitarian aspects throughout Yemen. We talked about releasing all prisoners and detainees from different parties", he told reporters after sitting down with Hadi. Following the meeting, the president set up a ministerial committee, supervised by the Prime Minister Ahmed Obeid bin Daghr, aimed at crystallizing ideas about consultations that should precede any direct negotiations between the warring parties and study any suggestions that may be put forward by the UNs envoy. It is the second trip by Griffiths to the temporary capital Aden in less than a month. He had informed the UN Security Council last Thursday about his plans to hold talks with Hadi and Saudi-led Arab coalition leaderships to place the outcome of his talks with both sides on paper, particularly Houthi militia pledges to put Hodeidah’s harbor under UN supervision. On Tuesday, Hadi accused the Iran-backed Houthis of prolonging the conflict in Yemen. “They do not understand the concept of peace. They just ostensibly agree to negotiate a peace settlement whenever they suffer setbacks in order to buy more time to plant landmines and cause more destruction and suffering for the Yemeni people", he said. He cited the ordeal of the people in Hodeidah and the atrocities committed by the Houthis. He also noted their control of the strategic Hodeidah port to smuggle weapons, squander humanitarian aid and exploit the harbors revenues to prolong its war against the people.
