CAIRO (AP) — Saudi officials were in Yemen’s capital Sunday for talks with the Iran-backed Houthi rebels, as part of international efforts to find a settlement to Yemen’s nine-year conflict, officials said.

Saudi Arabia’s delegation, chaired by the kingdom’s ambassador to Yemen, Mohammed bin Saeed Al-Jaber, will hold talks with with Mahdi al-Mashat, head of the Houthi’s supreme political council, which runs rebel-held areas in Yemen, according to the Houthi-run SABA news agency.

An Omani delegation, which arrived in Sanaa on Saturday, will also join the talks, the agency reported, citing an unidentified source.

Mohammed al-Bukaiti, a Houthi leader, said on Twitter that Saudi and Omani officials would discuss “ways to achieve a comprehensive and lasting peace in the region.”

He said achieving an honorable peace between the Houthis and Saudi Arabia would be “a triumph for both parties,” and urged all sides to take steps to “preserve a peaceful atmosphere and prepare to turn the page of the past.”

There was no immediate comment from Saudi Arabia.

In comments to the Associated Press, Hans Grundberg, the UN envoy for Yemen, described the ongoing efforts, including the Saudi and Omani talks in Sanaa, as “the closest Yemen has been to real progress towards lasting peace” since the war began.

“This is a moment to be seized and built on and a real opportunity to start an inclusive political process under UN auspices to sustainably end the conflict,” he said.

The talks in Sanaa are part of international efforts led by Oman to settle Yemen’s conflict, which began in 2014. That’s when the Houthis seized Sanaa and much of the country’s north, ousting the internationally recognised government that fled to the south and then into exile in Saudi Arabia.

The Houthi move prompted a Saudi-led coalition to intervene months later in a bid to restore the internationally recognised government to power. The conflict has in recent years turned into a regional proxy war between Saudi Arabia and Iran.

Saudi Arabia and the Houthis reached a draft deal last month to revive a cease-fire that expired in October. The deal is meant to usher in a return to Yemeni political talks, according to Saudi and Yemeni officials.

The officials spoke on condition of anonymity to discuss closed-door negotiations.

They said the Saudi-Houthi understandings include a six-month truce with a cessation of all military activities across Yemen. The Houthis have committed to coming to the table with other Yemeni parties to negotiate a political settlement to the conflict, they said. The United Nations is meant to facilitate the political negotiations, they added.

Both parties also agreed to further ease restrictions by the Saudi-led coalition on Sanaa’s airport and the Houthi-controlled Red Sea ports in Hodeida, the officials said. The Houthis would lift their yearslong blockade on Taiz, Yemen’s third largest city which is held by government forces, they said.

The phased roadmap also includes payment for all state employees — including the military — from oil and gas revenues. In return, the rebels agreed to allow exporting oil from government-held areas after a monthslong hiatus because of Houthi attacks on oil facilities, the officials said.

Yemen’s internationally recognised presidential council was briefed on the Saudi-Houthi understandings at a Thursday meeting in the Saudi capital, Riyadh, with Prince Khalid bin Salman, the Kingdom’s defense minister, a Yemeni official said.

The Saudi-backed council, which was appointed a year ago, has given its initial approval to the draft deal, the official said.
