Iran closed the Strait of Hormuz indefinitely and attacked a Cyprus-flagged container ship, which caught fire and forced its crew to evacuate. The U.S. launched retaliatory airstrikes early Sunday morning, with Iran subsequently striking targets in Bahrain, Qatar, and the UAE in response. This escalation follows the ongoing US-Israel war with Iran that began in late February 2026 after Ali Khamenei's death, and threatens a memorandum of understanding signed less than three weeks prior.
