U.S. President Donald Trump said he hoped the war against Iran was nearing an end, while the conflict entered its seventh month and expanded into Yemen. Saudi aircraft struck Yemen as Iran-backed Houthi fighters launched drones and missiles at Saudi cities, including the Red Sea oil port of Yanbu and an airbase at Khamis Mushait. The Houthis’ advance along the Red Sea and attacks that damaged Saudi Arabia’s East-West oil pipeline have increased concerns over global energy supplies. The United States tightened its Saudi Arabia travel warning, barring government employees from traveling within 20 miles (30 km) of the Yemen border. Trump said Iran wanted a deal and that he had heard from Iran directly, without providing details. The conflict began on February 28, when the U.S. and Israel attacked Iran and Tehran struck Israel and U.S. bases in Gulf states. Disruptions to shipping through the Strait of Hormuz, which carried about 20% of global oil and LNG before the war, have added to the energy-supply shortage. Traders say a prolonged shutdown of the East-West pipeline could remove as much as 4% of global oil supply, while Saudi Arabia has not said when operations may resume. Brent crude was around $108 a barrel on Wednesday, and U.S. diesel prices exceeded $6.30 a gallon for the first time. Prices eased early Thursday after reports that Saudi Arabia would offer additional crude cargoes through Oman. Axios reported that Trump was expected to meet Gulf leaders or foreign ministers on the sidelines of the U.N. General Assembly on Tuesday to discuss the conflict’s next steps.
