A Yemeni source revealed to Al-Jazeera the terms of the US envoy Timothy Lenderking's plan to stop the war in Yemen and the principles of the joint declaration, which was welcomed by the government of President Abd Rabbu Mansour Hadi and rejected by the Houthi movement.

The document of principles stipulates a comprehensive ceasefire, including stopping Saudi raids and Houthi drones, and also includes opening Sanaa airport, allowing fuel supplies to enter from the port of Hodeidah, and the return of consultations.

The source explained to Al-Jazeera that there is a disagreement between the Houthis and the US envoy regarding the mechanisms, details and conditions of the joint declaration of the ceasefire, stressing that the Houthis, in return, presented their vision to the US envoy on a comprehensive ceasefire in Yemen.

Saudi support

Lenderking revealed earlier on Friday that he had offered a few days ago a plan for a ceasefire in Yemen to the Houthis, and said that his country was waiting for a signal from them about it.

He added that Saudi Arabia "is ready to deal with the conflict in Yemen in a way it was not prepared to deal with 6 months ago, and it is determined to provide all support to the American efforts."

The US official said that he would return to the region "immediately when the Houthis are ready for dialogue," adding, "If we are unable to make progress now, the country will enter into conflict and greater instability."

The Houthis have recently continued a campaign on the Marib region, with the aim of wresting control of the last government stronghold in northern Yemen, and the United Nations has warned that millions of civilians are in danger.

"Tragically and somewhat embarrassing to me, it seems that the Houthis are prioritizing a military campaign to control Marib, rather than stopping the war and transferring aid to the Yemeni people," the US envoy said.

He announced that the United States will resume funding for humanitarian aid to northern Yemen, and said that Washington will work with the governments of Yemen and Saudi Arabia to find a way to deliver fuel to the Yemenis who need it most.

Houthi refused

The Houthi spokesman, Muhammad Abdul Salam, said that the US proposal "did not carry anything new," and that it "represents the Saudi and international vision."

Abdul Salam added - in statements carried by the Houthi-affiliated Al Masirah TV - that the US proposal is "just cosmetic detours that lead to the return of the siege," and "just a conspiracy to put Yemen in a more dangerous stage than it is now," as he put it.

For his part, Yemeni government spokesman Rajeh Badi said that the proposed US initiative is "a general outline agreed by the government out of concern for peace in the country."

In an interview with Al-Jazeera, Badi indicated that the main idea of ​​the initiative presented by Lenderking is a ceasefire and political dialogue.

In turn, the Yemeni Foreign Ministry said that the government responded to the initiatives of the new US administration regarding bringing peace to Yemen and dealt with it positively.

She added that the Houthis met these calls to open new fronts and escalate what it called the military aggression in Marib, Taiz and Hodeidah, and said that during last February, only 25 ballistic missiles were launched, causing hundreds of deaths and injuries.

The ministry considered that this escalation "seeks to completely eliminate the political track, end the outcome of many years of international political efforts, and undermine any hopes for peace in Yemen."
