The United Nations envoy to Yemen, Hans Grundberg, arrived in Sanaa on Monday to consolidate the truce that was announced earlier this month.
He is set to meet with leading members of the Iran-backed Houthi militias as part of his efforts to resolve the crisis.
A statement from his office said discussions will focus on the implementation and consolidation of the two-month UN truce. They will also tackle a comprehensive peace process that Grundberg is drafting.
The Houthis had refused to meet with Grundberg in September, shortly after he had assumed his post. He ended up meeting with their negotiations delegations on several occasions in the Omani capital Muscat.
The Omani Foreign Ministry revealed that envoy's visit to Sanaa was possible after a series of meetings and discussions between Oman's Foreign Minister Badr Albusaidi and head of the Houthi negotiations delegation Mohammed Abdulsalam.
In a tweet, the ministry said the talks focused on consolidating the truce and the conditions needed to reach a comprehensive settlement in Yemen.
