"We welcome any efforts to help end the war in Yemen and de-escalate tensions in Mideast."

"De-escalation and diplomacy together with deterrence are key pillars of the policy President Biden outlined during his visit to the region last year," the White House spokesperson told Reuters.

Iran and Saudi Arabia agreed on Friday to reestablish diplomatic relations and reopen embassies after years of tensions between the two countries in a deal that was brokered by China.

The US is advocating for diplomatic means to prevent Iran from acquiring nuclear weapons.

Israel, the US closest ally in the Middle East, has not ruled out the possibility of military action to achieve the same objective.

US Defense Secretary Lloyd Austin has recently visited Israel and discussed the issue with Israeli Defense Minister Yoav Gallant.

Austin reiterated the US's stance on diplomacy, while Gallant emphasized that "all measures necessary" must be taken to prevent Iran from acquiring nuclear weapons.

The Biden administration is seeking to revive the 2015 nuclear deal, which gave Iran relief from economic sanctions in exchange for curbs on its nuclear program.

However, talks have stalled for months, and the recent reconciliation between Saudi Arabia and Iran has added an additional layer of complexity to an already delicate situation.

The Iran Saudi reconciliation agreement could have wide implications for the war in Yemen, where Iran-backed Houthi rebels have been fighting a Saudi-led coalition since 2015.

Agreement could pave the way for a political solution to end the conflict and alleviate humanitarian crisis.
