The Iran war broadened over the weekend despite a pause in U.S. strikes, as Yemen's Ansar Allah attacked Saudi oil installations along the Red Sea coast and Iran accused Ukraine of targeting one of its vessels in the Caspian Sea.
The US military said on Saturday its naval blockade against Iran "remains in full effect" but did not explain why it halted a streak of 13 nights of escalating strikes.
There were also no weekend reports of attacks by Iran on neighbors, similar to its daily rejoinders to the US attacks.
Asked about the pause, a senior official in President Donald Trump's administration said Trump "has always been clear that his preference is diplomacy, but he has shown Iran what will happen if they fail to come to the table seriously."
Trump has decided, for now, to back away from plans to ramp up attacks on Iran, the New York Times said on Saturday, citing two people briefed on the discussion.
The president and his advisers, the newspaper said, have concerns about expanding the conflict, depleting defense stockpiles, alienating Middle East Gulf allies and affecting energy supplies and the global economy.
Vice President JD Vance and Gen. Dan Caine, the chairman of the Joint Chiefs of Staff, both raised concerns about the U.S. munitions stockpile with Trump during a White House meeting on Friday, a U.S. official told CNN.
Operations are "on a hold," a Department of Defense source told the broadcaster on Saturday.
Despite the Gulf lull, Saturday's fighting between Ansar Allah and Saudi Arabia showed that the war, which has already disrupted energy supplies through the Strait of Hormuz, could affect a second major shipping route and reignite Yemen's civil war.
Separately, Iran's Foreign Ministry accused Ukraine of attacking an Iranian commercial vessel in the Caspian Sea, saying one sailor was killed and another injured.
The ministry summoned Ukraine's chargé d'affaires in Tehran to protest over an attack it described as "hostile and criminal", state news agency IRNA said.
The Iranian denunciation coincided with comments by Ukrainian President Volodymyr Zelenskiy that Kyiv had noted Russia was passing on to Iran its satellite observations in the Middle East, to enable it to direct strikes in the region.
WAR THREATENS TO SPREAD TO YEMEN
Houthi military spokesperson Yahya Saree said the group struck sites belonging to Saudi state oil company Aramco in the cities of Jizan and Yanbu on Saturday.
A large column of smoke rose from the direction of the Aramco refinery in Jizan, near the Yemeni border, video on social media verified by Reuters showed. The refinery can process up to 400,000 barrels of crude oil daily.
Two Asia-based trading sources said they had been informed of potential damage to fuel and oil storage sites at Jizan. Aramco did not respond to requests for comment.
In Yanbu, two missiles aimed at oil installations were intercepted. Yanbu, Saudi Arabia's main Red Sea oil port, has become a key route for Saudi oil skirting the Strait of Hormuz, which Iran has blockaded.
SAUDI-LED COALITION STRIKES HODEIDAH
In Yemen, officials said the air force of the internationally recognised government, which has opposed the Ansar Allah for more than a decade, struck sites in the Marib and al-Jawf provinces.
The officials said both sides in Yemen's civil war were mobilising forces along the front.
