The UN special envoy for Yemen, Martin Griffiths on Tuesday departed the Yemeni capital of Sana'a following a 24-hour unfruitful visit during which he met with the Houthi leader, Abdul Malik al-Houthi.
The UN envoy arrived Monday in the Houthi-held capital, after two-day delay for logistic reasons, to helpimplement the Hodeida redeployment first phase under the stalled Stockholm Agreement.
Griffiths' meeting with the Houthi leader was "unfruitful", a Yemeni firsthand source told Debriefer Monday on condition of anonymity.
"The UN envoy and Houthi leader have reached no complete deal on implementing the Stockholm Agreement" reached by warring parties last December, the source added without further details.
At arrival, departure and meeting, Envoy Griffiths gave no comments to reporters at Sana'a airport.
Yemen has been racked by an armed conflict that broke out after the Iranian-backed Houthis had ousted the internationally recognized government late in 2014.
The conflict escalated after a Saudi-led coalition intervened militarily in the country in March 2015 to reinstate the government of President Hadi.
Parties to the 4-year war in Yemen, after 8-day peace talks in Sweden, reached on the 13th of last December an agreement providing for ceasefire in Hodeida and redeployment of both sides' forces, exchanging prisoners and alleviating blockade imposed by Houthis on Taiz.
But none of this has taken place so far, with both sides trading blames for trying to thwart the deal.
The port city of Hodeida and its three ports have been under Houthi control since late 2014, while Yemeni joint forces loyal to legitimate government and Arab coalition have massed at the city's fringes since last November seeking to retake the strategic port.
Yemen 4-year war has left most of the population in need for a type of humanitarian aid and immediate protection, including 14 million people risking famine and some 1.8 million children suffering malnutrition.
