UKMTO said it received reports of an incident in the Strait of Hormuz; tankers reported being struck by an unidentified object, causing engine-room damage.

Saudi-led coalition said on the 3rd that Houthi claims of an attack on Riyadh were "misleading." Coalition spokesman Turki al-Maliki said losses the Houthis suffered in Taiz province and other fronts have prompted them to seek a "false victory" to divert attention. Earlier on the 3rd the Houthis said they used ballistic missiles and drones to strike an ARAMCO oil facility in Riyadh, achieving their objectives and "directly hitting" the target and causing a fire. The Houthis framed the strike as retaliation for Saudi strikes on Sanaa and other Houthi-held areas.

Treasurer Jim Chalmers told ABC’s Insiders the US conflict with Iran has become an economic disaster that is raising global inflation and borrowing costs and weighing on growth.
