U.S. airstrikes targeting Iranian drones and naval vessels aim to restore shipping traffic, which has nearly ceased since the onset of conflict three weeks ago. In response to President Trump’s ultimatum, Iran has threatened retaliatory strikes on American and Israeli energy infrastructure. Concurrently, Riyadh reported a missile attack on its capital, with one of three incoming missiles intercepted; the origin of the attack remains uncertain, though suspicions point to Iran. Saudi Arabia has since expelled several Iranian diplomats and a senior military officer.
