U.S. President Donald ​Trump said he hoped an end to the war against Iran was near, as the conflict, in its seventh month, escalated with ‌Saudi aircraft pounding Yemen and Houthi fighters launching drones and missiles at Saudi cities.

The Iran-backed Houthis’ ​lightning advance in Yemen along the Red Sea and their attacks on Saudi Arabia, along with attacks ⁠that damaged Saudi Arabia’s East-West oil pipeline, have extended Tehran’s reach in the war and heightened global oil-supply risks.

As the war expands into a new theatre, the United States tightened its travel warning for Saudi Arabia, banning government employees from travelling within 30 ‌km (20 miles) of the Yemen border.

Still, just hours after reports of the Houthis and Saudi Arabia fighting, Mr. Trump told reporters on Wednesday (September 16, 2026) evening: “Well, hopefully we are towards the end of the war.”

‘Iran wants a deal, oil price still elevated’

“They want to make a deal. We’ll see how that works ‌out,” ⁠he said, referring to Iran, reiterating past comments. Mr. Trump also said he had heard from Iran “directly”, without ⁠elaborating.

Mr. Trump has offered shifting goals and timelines for the war that began on February 28, when the U.S. and Israel attacked Iran and Tehran struck Israel and U.S. bases in Gulf states.

The extension of the war into Yemen threatens to worsen the global energy-supply shortage caused by ​the war, which has disrupted shipping through the Strait ‌of Hormuz. The strait carried about 20% of global oil and LNG before the conflict.

Traders say a prolonged closure of Saudi Arabia’s East-West pipeline could cut off as much as 4% of global oil supply. Saudi Arabia has not said when operations might resume.

The price of Brent crude hovered around $108 a barrel on Wednesday (September 16, 2026), close ‌to its highest levels since May. The politically sensitive average retail price of diesel fuel in the U.S. ​hit another all-time high, above $6.30 a gallon for the first time.

But oil prices fell in early Thursday (September 17, 2026) trade as reports of Saudi Arabia offering extra crude cargoes through Oman reduced fears of ⁠supply disruptions in the West Asia

Brent crude futures dropped $1.24, or 1.2%, to $104.59 a barrel by 0049 GMT, while U.S. West Texas Intermediate futures were down $1.14, or 1.1%, at $101.29.

The rise in oil and gas prices due to the U.S.-Israeli war on Iran ‌has become a major issue for Mr. Trump’s Republican Party in the lead-up to November midterm elections.

Trump to meet Gulf leaders as war spreads

Axios reported late on Wednesday (September 16, 2026) that Mr. Trump was expected to meet Gulf leaders on the sidelines of the UN General Assembly on Tuesday (September 22, 2026) to discuss the next steps in the conflict.

Citing sources it did not identify, the news outlet said Mr. Trump would meet with leaders or Foreign Ministers from the Gulf Cooperation Council countries: Saudi Arabia, the United Arab Emirates, Qatar, Bahrain, Kuwait and Oman. The State Department and the White House did not ‌respond to requests for comment.

The Houthis on Wednesday (September 16, 2026) released battlefield video of fighters seizing armoured vehicles from Saudi-backed forces. The video also showed ​warplanes flying overhead and huge explosions billowing into the sky from desert dunes.

Houthi military spokesman Yahya Saree said the group had launched fresh drone and missile strikes on the major Saudi Red Sea ⁠oil port of Yanbu and at a southern Saudi airbase at Khamis Mushait. He did not say when the strikes had ⁠taken place.

Houthi military spokesman Saree said the Saudis had carried out as many as 450 air strikes on Yemen this week. Officials in the Saudi-backed government that controls southern Yemen have acknowledged that their forces and those of ‌Saudi Arabia were conducting air strikes on Houthi positions, though Riyadh has not confirmed them.

Saudi Arabia has led a coalition battling the Houthis since 2015. The conflict had largely quietened under a ceasefire in recent years, but reignited ​when the Houthis declared a naval blockade against Saudi Arabia in July and fired at southern areas in the kingdom.

The top diplomats of Iran and Saudi Arabia spoke by phone to discuss “growing insecurity” in the region, Tehran said, without mentioning recent fighting in Yemen, where the two countries support opposing sides.

Tehran militarily and financially backs Yemen’s Houthis, who for years have held large parts of the country’s north and on Thursday (September 10, 2026) seized the strategic Red Sea port city of Mocha.

Riyadh has long supported Yemen’s internationally recognised government and has been carrying out airstrikes on the Houthis since they began their advance, the group has said.

Saudi Arabia and Iran have also found themselves at odds during the wider West Asia war, which saw Tehran launch strikes on Saudi oil infrastructure and U.S.-linked targets in the Gulf kingdom.

Iranian top diplomat Abbas Araghchi spoke with his Saudi counterpart Faisal bin Farhan on Thursday (September 10, 2026) evening about “the escalation of tensions and the growing insecurity in the region”, according to Tehran’s foreign ministry.

The summary of the call said the two parties “emphasised the need to continue cooperation and diplomatic efforts in order to prevent the spread of tensions and reestablish stability”.

Though the ministry did not specifically mention Yemen in the readout, a separate statement addressing the fighting there insisted it was “impossible to resolve the Yemeni crisis through… military intervention”.

The Houthis have controlled Yemen’s capital Sanaa and the major port city of Hodeida for years, but in recent days have launched a new offensive pushing towards the strategic Bab al-Mandab strait, the gateway to the Red Sea.

The waterway, which links Asia to Europe via the Suez Canal, has gained importance as a transit route since the start of the wider West Asia war, which saw Iran blockade the Strait of Hormuz.

Dangerous phase: On the crisis in West Asia

With their drones and missiles, the Houthis have been able to disrupt traffic in the Red Sea and have also sought to enforce a maritime blockade on Saudi ports, while striking oil infrastructure there.

Yemen relapsed into war in July after years of relative calm, punctured by sporadic violence and deepening poverty.

On Wednesday (September 9, 2026), the Saudi-led coalition battling the Houthis said the group fired ballistic missiles and drones at several cities in southern Saudi Arabia.
