The UN Envoy for Yemen left on Wednesday the Yemeni capital of Sana'a after meeting in one-day visit Houthi leader and other officials.
Martin Griffiths and accompanying delegation left Sana'a airport Wednesday noon, said local sources at the airport.
The UN envoy's talks focused on the offer announced by Houthi group on 20 September to halt all its strikes on Saudi Arabia, as part of "peace initiative aimed at national inclusive conciliation" under talks between all parties.
Talks also discussed the UN peace efforts to establish the Hodeida truce in preparation for Stockholm Agreement's application.
Parties to the 4.5-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.
Earlier on Wednesday, Griffiths tweeted that his meeting with Abdul Malik al-Houthi was fruitful, as it addressed means to build on the group's recent initiative in support of immediate de-escalation and to resume peace process in Yemen.
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.
