- U.S. Central Command struck missile and drone locations and coastal radar sites in Iran on Friday June 26, 2026, roughly an hour after announcing the operation, in retaliation for a drone attack a day earlier on a cargo ship in the Strait of Hormuz.
- Iran's Revolutionary Guards said Saturday June 27 they targeted U.S. military positions in the region; an earlier IRGC statement carried by ISNA promising a "swift and decisive" response was later deleted from the agency's site.
- Ebrahim Azizi, head of Iran's parliament national security commission, defended the cargo ship strike as "ceasefire management" rather than a ceasefire violation, telling the U.S. to "respect the rules" of Iran's strait control.
- The International Maritime Organisation halted its operation to evacuate roughly 500 stranded ships via an alternative route hugging Oman's coast after the attack — about 115 vessels had already transited before evacuations were suspended.
- Marine data showed 78 vessels transited the strait on Wednesday June 24, the highest daily count since the war began, but the pace slowed after the strike and at least two tankers reversed course near Oman when Iran insisted on Tehran-approved routes.
- Under the interim deal, the U.S. and Iran have 60 days to negotiate permanent terms covering Hormuz passage and the future of Iran's stockpile of highly enriched uranium.
Why it matters: The first armed exchange since the interim ceasefire now threatens a deal that had been unlocking the Strait — 78 transits on June 24 showed normalization was accelerating, but the cargo ship strike, IMO evacuation halt, and at least two tankers reversing course near Oman demonstrate Iran's leverage over the waterway remains intact. With roughly 500 vessels still stranded and the 60-day negotiation window now under far greater pressure, the path to resolving Iran's enriched uranium stockpile alongside shipping terms is markedly harder.
