The main negotiator of Yemen's Iran-aligned Houthi group called on Saturday for the formation of a transitional government with the participation of "all political parties".
Yemen's warring sides agreed to free thousands of prisoners on Wednesday, in what a UN mediator called a hopeful start to the first peace talks in years to end a war that has pushed millions of people on the verge of starvation.
UN mediator Martin Griffiths told a news conference in a renovated castle outside Stockholm that just getting the warring sides to the table was an important milestone.
The war has killed tens of thousands of people and spawned what the United Nations calls the world's direst humanitarian crisis, since a Saudi-led Arab coalition intervened in 2015 to restore a government ousted by the Iran-aligned Houthi movement.
No talks have been held since 2016, and the last attempt in Geneva in September failed when the Houthis did not attend.
