UN special envoy Martin Griffiths arrived in the Yemeni capital Sana’a on Monday to escort the Houthi delegation.
The peace talks may start Wednesday, two sources familiar with the matter said, Reuters reported.
Griffiths shuttled between the parties to salvage a previous round that collapsed in September after the Houthis were barred from joining the talks.
Mohammad al-Bukhaiti, a member of the Houthi political bureau, said its delegation would travel to Sweden Tuesday morning on a plane provided by Kuwait and accompanied by Griffiths.
A post on the UN envoy’s Twitter account thanked all parties for facilitating the evacuation of the 50 wounded fighters Monday to Oman for treatment.
A plane carrying the wounded arrived in Muscat Monday night, fulfilling one of the conditions that had been set by the Houthi Ansarullah movement to participate in the talks.
Some 8.4 million Yemenis are facing starvation as a result of the Saudi-led aggression, although the United Nations has warned that will probably rise to 14 million.
Three-quarters of impoverished Yemen’s population, or 22 million people, require aid.
