US Special Envoy for Yemen, Tim Lenderking, on Wednesday called on the Houthi group to show more flexibility over an extended and expanded truce deal proposed by the United Nations to build on a previous pact that expired on Sunday, Reuters reports.
An initial truce, first agreed in April, had brought the longest stretch of relative calm in the seven-year-old conflict between a military coalition led by Saudi Arabia and the Iran-aligned Houthis.
Lenderking said in a news briefing that the Houthis, de facto authorities in North Yemen, had "imposed maximalist and impossible demands" over a proposed mechanism to pay public sector wages, but that he was confident agreement could be reached if the group showed flexibility.
A member of the Houthi negotiating committee had, in a Twitter post, criticised the proposed payment scheme for not including members of police, security and military forces.
UN-led negotiations and US diplomacy "continue unabated", Lenderking said, adding that key elements of the initial truce were still holding – relatively low violence, fuel shipments to Hodeidah port and continuity of commercial flights from the capital, Sana'a, both held by the Houthis.
UN Envoy, Hans Grundberg, had told Reuters the two sides failed to renew the truce because they were still far away on proposals to pay civil service wages, increase fuel shipments, add air flights and open roads.
"I'm confident … that we can get there if the Houthis move away from the very high demands that they have levied," Lenderking said.
He also criticised recent Houthi statements threatening commercial shipping and oil companies and said the United States would continue to help its Gulf Arab partners defend themselves.
The truce has seen a halt to major military operations between the warring sides in Yemen, including coalition air strikes and Houthi cross-border drone and missile attacks on Saudi Arabia and the United Arab Emirates.
The Saudi-led coalition intervened in March 2015, after the Houthis ousted the internationally recognised government from Sana'a. The conflict has killed tens of thousands, devastated Yemen's economy and pushed millions into hunger.
