Breaking — May 10, 2026: May 5–8, 2026 has been the most violent 4-day period of the Hormuz crisis for commercial shipping. CMA CGM San Antonio was struck by a cruise missile injuring 8 crew. Chinese tanker JV Innovation was attacked — the first Chinese vessel targeted in the crisis. Iran seized oil tanker Ocean Koi on May 8. This incident log covers every major attack and seizure during this period and what each means for Dubai cargo shippers operating right now.
May 5, 2026 — CMA CGM San Antonio Hit by Cruise Missile
On May 5, 2026, the CMA CGM San Antonio — a container vessel operated by French carrier CMA CGM — was struck by a cruise missile in the Strait of Hormuz. Eight crew members were injured in the attack. CMA CGM confirmed the incident and identified the vessel. This was one of the most significant direct attacks on a major Western carrier’s vessel during the entire crisis. CMA CGM has been operating alternative routing via the Cape of Good Hope for most of its Asia-Europe services since the crisis began — but the San Antonio was apparently attempting a Hormuz transit when it was hit. The attack came on the same day the US launched Operation Project Freedom. For the Project Freedom context: Trump Pauses Project Freedom — Full Analysis.
May 5, 2026 — US Destroys Six Iranian Boats
On the same day as the CMA CGM San Antonio attack, the US military destroyed six small Iranian boats in the Strait of Hormuz. US Central Command chief Admiral Bradley Cooper confirmed that Iran had launched “multiple cruise missiles, drones and small boats” against US Navy ships and commercial vessels under US protection. Trump stated the US shot down “seven small” Iranian boats — a slight discrepancy from CENTCOM’s account. Iran disputed the US version of events in state media. This naval confrontation on May 4–5 was the most direct US-Iran military engagement since the ceasefire was announced on April 7.

May 7, 2026 — Chinese Tanker JV Innovation Attacked
On May 7, 2026, Caixin reported that the Chinese chemical tanker JV Innovation was attacked near Mina Saqr, UAE — marking the first time a Chinese-owned vessel was targeted during the entire Hormuz crisis. The vessel reported a fire on board to other vessels near Mina Saqr on May 4 and the attack was subsequently confirmed on May 7. US envoy to the UN Mike Waltz accused Iran of conducting the attack. This is a strategically significant development because Iran had previously permitted Chinese vessels to transit the Strait — citing China’s “supportive stance.” The attack on a Chinese vessel signals that Iran’s tolerance for even permitted nations may be breaking down under pressure from IRGC hardliners.

May 8, 2026 — Iran Seizes Oil Tanker Ocean Koi
On May 8, 2026, Iran seized the oil tanker Ocean Koi, accusing it of “trying to harm and disrupt oil exports.” The Ocean Koi had been sanctioned by the US in February 2026 on accusations of transporting Iranian oil as part of Iran’s shadow fleet. Iran’s seizure of the vessel was framed as a counter-measure — taking back a vessel that the US had sanctioned for helping Iran. For Dubai cargo shippers, this seizure is significant because it demonstrates that Iran is willing to seize vessels directly — not just attack them — and that the IRGC is actively using maritime seizures as a diplomatic and economic tool. Any vessel with prior US sanctions exposure is at extremely high risk of seizure if it enters Iranian-controlled waters.

What These Incidents Mean for Dubai Cargo Shippers
CMA CGM San Antonio — Impact on French Carrier Services
CMA CGM is one of the world’s top three carriers and a major provider of Europe-Dubai freight services. The San Antonio attack will likely cause CMA CGM to further restrict any remaining Gulf routing. Dubai shippers using CMA CGM for European imports should expect continued Cape of Good Hope routing or potential service disruptions. Contact your CMA CGM freight forwarder to confirm current routing for all active bookings. For current shipping costs and alternatives: Dubai Cargo Update May 2026.
JV Innovation Attack — Chinese Vessel Risk Has Increased
The attack on JV Innovation is the most alarming development for Dubai shippers using Chinese freight services or Chinese-flagged vessels. If Iran is now targeting even Chinese vessels — which had been the primary permitted nationality for Hormuz transit — then no vessel can be considered safe in the Strait regardless of flag or ownership. Dubai shippers should immediately stop assuming Chinese-flagged routing offers Hormuz safety. All Gulf routing carries extreme risk as of May 7, 2026.
Ocean Koi Seizure — Sanctions-Exposed Vessels at Extreme Risk
Any vessel that has previously been sanctioned by the US or associated with Iranian oil shadow fleet operations is now at extreme risk of seizure if it operates anywhere near Iranian-controlled waters. Dubai freight forwarders should immediately audit the sanctions status of any vessels being used for Gulf-adjacent routes and avoid any vessel with prior OFAC sanctions history.
Current Shipping Costs — May 10, 2026
| Route and Mode | Current Cost May 10 | Status | Recommended? |

| Sea via Khor Fakkan | $1,200–$1,800 FCL 20ft | ✅ Safe — outside Gulf | ✅ Yes |
| Sea via Fujairah | $1,100–$1,600 FCL 20ft | ✅ Safe — outside Gulf | ✅ Yes |
| Land freight — Saudi Arabia | AED 180–280 per 100kg | ✅ Fully safe | ✅ Yes |
| Land freight — Oman | AED 120–200 per 100kg | ✅ Fully safe | ✅ Yes |
| MSC Saudi land bridge (Europe) | $2,800–$4,000 FCL 20ft | ✅ Safe — Hormuz-free | ✅ Yes |
| Air cargo DXB | AED 18–28 per kg | ✅ Safe — elevated rates | ✅ Urgent only |
Immediate Actions for Dubai Cargo Shippers
- Stop all Gulf sea routing immediately — May 5–8 incidents confirm Hormuz is too dangerous for any commercial vessel regardless of flag
- Verify CMA CGM active bookings — contact your forwarder to confirm San Antonio attack has not affected your shipment schedule
- Do not rely on Chinese-flagged vessels for Hormuz safety — JV Innovation attack invalidates this assumption
- Check vessels for OFAC sanctions history — Ocean Koi seizure shows Iran actively targets sanctioned vessels
- Route all sea freight via Khor Fakkan or Fujairah — both fully operational and completely outside the risk zone
- Book land routes for all GCC destinations — Saudi, Oman, Qatar land corridors are 100% unaffected by all May incidents
Frequently Asked Questions — May 2026 Hormuz Incidents
Was anyone killed in the CMA CGM San Antonio attack?
Eight crew members were injured. No fatalities were reported. The vessel was struck by a cruise missile in the Strait of Hormuz on May 5, 2026. CMA CGM confirmed the incident and the vessel was subsequently taken out of service for emergency repairs.
Why did Iran attack a Chinese vessel?
Iran had previously permitted Chinese vessels to transit Hormuz. The JV Innovation attack on May 7 may indicate IRGC hardliners overriding the political decision to permit Chinese transit, or it may indicate the vessel was not clearly identifying its Chinese ownership at the time of attack. US envoy Mike Waltz accused Iran of conducting the attack. China has not made an official public statement confirming vessel nationality at time of attack.
What happened to the crew of Ocean Koi after Iran seized it?
No crew casualty reports have been confirmed as of May 10, 2026. The vessel was seized and detained by Iran. The crew’s status and any diplomatic negotiations for their release have not been publicly disclosed. This is an evolving situation — monitor updates from your freight forwarder and carrier.
Is it still safe to ship cargo through Dubai?
Yes — Dubai’s port infrastructure, customs, and land logistics are fully operational and safe. All attacks have occurred in the Strait of Hormuz or the Persian Gulf — not at Dubai Port itself. The Kuwaiti tanker Al Salmi was struck at Dubai Port on March 31, but no further incidents have occurred at the port itself. Use Khor Fakkan, Fujairah, and land routes as described above.
How do I know if my cargo’s vessel has OFAC sanctions history?
Ask your freight forwarder directly and request the vessel IMO number. Check it against the OFAC SDN (Specially Designated Nationals) list at sanctionssearch.ofac.treas.gov. Also check OFAC’s maritime sanctions advisory database. Any vessel previously associated with Iranian oil transport or with a sanctions designation should be avoided entirely for all Gulf-adjacent routing.
