Iran's foreign ministry condemned a Ukrainian attack on an Iranian commercial vessel in the Caspian Sea, saying it resulted in an explosion that killed one sailor and injured another.

The Iranian foreign ministry summoned Ukraine's chargé d'affaires in Tehran to convey its protest over what it described as a "hostile and criminal" attack, Iran's state news agency IRNA reported.

The Iranian denunciation coincided with comments by Ukrainian president Volodymyr Zelensky that Kyiv had noted Russia was passing on its satellite observations in the Middle East to Iran to enable it to direct strikes in the region.

Throughout the war in Ukraine, Kyiv said it has had to counter Iranian-designed drones deployed by Moscow. Ukraine has offered its drone interception expertise to countries in the Middle East that have suffered strikes from Iran.

Earlier, US president Donald Trump told French News Channel LCI, he is considering resuming a full-scale war with Iran “if we don’t get 100% of what we want”.

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.

In Yemen, officials said the air force of the Saudi-backed, internationally recognised government, which has opposed the Houthis for more than a decade, struck Houthi sites in the Marib and al-Jawf provinces.

The officials said both sides in Yemen's civil war were mobilising forces along the front. Saudi Arabia has led an Arab coalition battling the Houthis since the Iran-aligned fighters captured Yemen's capital, Sanaa.

Iran war spreads to Red Sea and Caspian but Gulf quiet as US forgoes strikes

The Iran war broadened over the weekend despite a pause in US strikes, as Yemen's Iran-aligned Houthis 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 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 neighbours, 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 in a serious way".

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.

Trump went on expletive-laden rant against ‘scumbags’ in Iran as his frustration with war mounts: report

President Donald Trump unleashed an expletive-filled rant against Iran’s leaders as he appears to be increasingly frustrated with the lack of progress in the war he started earlier this year, according to a report.

During a recent Oval Office meeting, the president called the Iranian leaders “scumbags” and “lunatics,” a person who overheard the remarks told The Wall Street Journal.

Roughly five months into the U.S.-Iran conflict, there has been limited progress on a peace deal, which has seen lengthy negotiations between the two sides.

Experts warn the real pinch from the Iran war is about to strike

US gas prices will continue climbing for weeks — and maybe months — due to the resumption of President Donald Trump’s war against Iran, experts warn.

Patrick DeHaan, petroleum analyst for GasBuddy, said Friday on social media that while oil prices were “taking a breather for today” after recently surging by $20 a barrel, he’s still expecting the national average cost of a gallon of gas to soon reach $4.20 to $4.30.
