The UN Security Council on Friday called on the Houthis to immediately open roads in Taiz and reach a political solution.
The Council welcomed the extension of the truce in Yemen for an additional two months, but expressed "serious concern" about the humanitarian consequences of road closures in Taiz.
The Council praised "the measures taken by the authorities in Yemen to maintain the truce".
The Council also expressed the hope that the strengthened truce would translate into a permanent ceasefire and a comprehensive political settlement, under the auspices of the United Nations, calling on the Yemeni parties to continue their participation with the UN envoy, negotiate and communicate with each other in a spirit of mutual respect and reconciliation.
On Friday, the Yemeni government blamed the Houthi militia for stalling negotiations to open crossings and roads in Taiz under the auspices of the United Nations in Amman, Jordan.
The head of the government negotiating team Abdul Karim Cheban, in a press release, said that his team is in Amman, pointing out that the continued absence of the delegation of the other party for days hinders the progress of the negotiations, which he hoped will end with the response to the opening of the main roads, especially the Road of Al-Houban - the city of Taiz.
The head of the government negotiating team reiterated his commitment to seeking all ways to end the Houthi militia's siege of Taiz, putting the world before the reality of the party obstructing the truce agreement and the continued suffering of the Yemeni people.
"We are reacting positively to put the whole world in the face of the reality of the embargo, the reality of who is doing it, and obstructing its implementation by all means," he said.
Sheban said the continued absence of the delegation of the other party (Al-Houthi) for days is hampering the progress of the negotiations.
He pointed out that this absence comes despite the end of the first period of the truce, the extension of it, and the implementation of the government's commitments to open Sana'a airport and the port of Hodeidah, but we find that the Houthis did not fulfill their obligations to open the main roads to the city of Taiz and supply the amounts collected from the port of Hodeidah to the Central Bank to pay the salaries of employees in Sana'a and the rest of the provinces under their control.
