A gunboat of Iran’s Islamic Revolutionary Guard Corps (IRGC) opened fire on a commercial container ship approximately 15 nautical miles northeast of Oman on Wednesday, causing heavy damage to the vessel’s bridge, maritime authorities and Iranian state media confirmed.
The United Kingdom Maritime Trade Operations (UKMTO) said the ship’s master reported the IRGC gunboat approached the vessel and fired after warnings were ignored. No fires or environmental impact were reported from the incident, and all crew members were confirmed safe.
Iran’s semi-official Tasnim News Agency said the action constituted enforcement of “maritime law” after the ship failed to heed repeated warnings from Iranian forces. Tasnim published the report alongside the earlier UKMTO advisory.
The incident marks a significant escalation in the maritime dimension of the Iran crisis. Previous IRGC actions since the US-Israeli strikes on Iran began on February 28 have involved boarding, interdiction and harassment — this is the first confirmed armed attack on a commercial vessel, widening the threat to international shipping in the Gulf of Oman approaches.
The attack follows the US Navy boarding of the M/T Tifani in the Indian Ocean on April 21 and earlier enforcement of the US blockade of Iranian ports. It comes one day after President Donald Trump extended the Iran ceasefire indefinitely at Pakistan’s request, while maintaining the naval blockade on Iranian shipping.
Armed attacks on commercial vessels typically trigger immediate spikes in war-risk insurance premiums and force rerouting, with knock-on effects on freight costs for import-dependent economies including Sri Lanka. The Panama Canal auction bids have already surged to $4 million as Asian refiners seek alternative supply routes.
