RIYADH, Saudi Arabia - Riyadh is in talks with Yemen's Houthi rebels in a bid to end the country's civil war, a Saudi official said on Wednesday, in the first official confirmation of dialogue between the two sides.

The comment came after Saudi Arabia brokered a power-sharing agreement between Yemen's internationally-recognized government and southern Houthi separatists. Observers say it could pave the way for a wider peace deal.

"We have had an open channel with the Houthis since 2016. We are continuing these communications to support peace in Yemen," a senior Saudi official told reporters.

"We don't close our doors with the Houthis."

The official, who declined to be named, gave no further details on the talks but the development came after the rebels' missile and drone attacks on Saudi cities spiked over the summer, followed by a lull in recent weeks.

There was no immediate comment from the Houthi rebels, who seized Yemen's capital Sanaa and much of the country's north in 2014, sparking a Saudi-led military intervention in March 2015.

Washington too is in talks with the Houthis, US Assistant Secretary of Near Eastern Affairs David Schenker said during a visit to Saudi Arabia in September.

He did not say whether Washington was holding talks separately with the rebels, but analysts say it was likely happening in consultation with Saudi Arabia, a key ally in the Middle East.

The Saudi-led coalition intervened in Yemen in 2015 as the Houthis closed in on second city Aden, prompting President Abedrabbo Mansour Hadi to flee to Saudi Arabia.

Riyadh had reportedly hoped for a quick win against the Houthis, but instead waded into a quagmire that has cost it billions of dollars and hurt its reputation, while devastating the Arab world's poorest country.

The confirmation of talks also came amid the slow implementation of a landmark cease-fire deal in rebel-held Hodeida, which was reached by the Yemeni government and the Houthis in Sweden late last year.

The deal was hailed as Yemen's best chance so far to end the four-year conflict, but it appears to be hanging by a thread with breaches reported by both sides.

"If the Houthis (are) serious to de-escalate and accept to come to the table, Saudi Arabia will support their demand and support all political parties to reach a political solution," the Saudi official said.

The Houthis, on their part, have offered to halt all attacks on Saudi Arabia as part of a wider peace initiative, later repeating their proposal despite continued airstrikes by the Saudi-led coalition.

The offer came after the Houthis claimed responsibility for attacks on Sept 14 against two key Saudi oil installations that temporarily knocked out half of the OPEC giant's production.
