A Strait of Hormuz tanker attack disclosed three days late shows how dangerous Gulf shipping remains. On Monday, Oct. 26, 2026, the UK Maritime Trade Operations agency (UKMTO) said an outbound tanker was struck by an unknown projectile in the strait on Oct. 23 and disabled, while a separate vessel was reported on fire in the northern Persian Gulf off Iraq.
UKMTO said it had received a verified, time-late report of the strike, which happened at 0839 UTC on Oct. 23, according to gCaptain. The crew were reported safe, and no damage assessment or environmental impact had been reported, the agency said. It did not name the tanker. UKMTO said earlier this month that most incidents were going unreported because shipowners were declining to share information with its voluntary reporting center, Seatrade Maritime News reported.
Vessel on fire off Iraq’s Al-Faw
In a second warning Monday, UKMTO said it had received multiple third-party reports of a vessel on fire about 63 nautical miles southeast of Al-Faw, Iraq. The ship’s identity, the condition of its crew and the extent of damage were unknown, and UKMTO classed the event as suspicious activity rather than a confirmed attack, gCaptain reported. Maritime security firm Orbital Risk Intelligence said a vessel had been attacked off Basra and was burning, and a NASA satellite detected heat from the area at 0926, according to Seatrade. Attacks that far north have been less common, but Iran has shown it can reach vessels across the Gulf.
Strait of Hormuz tanker traffic and a “severe” threat level
The Joint Maritime Information Center (JMIC), a multinational naval coordination body, kept its threat assessment for the strait at SEVERE in an Oct. 25 advisory and said further deliberate attacks were highly likely. It counted 156 confirmed maritime security incidents across the region since March 1, a tally published before the latest tanker report. JMIC rated the wider Persian Gulf as SUBSTANTIAL, citing five attacks inside the Gulf since Oct. 7, and noted that an LPG tanker was hit by an unidentified projectile on Oct. 22 about seven nautical miles northeast of Limah, Oman.
Traffic remains far below normal. JMIC reported 101 U.S.-facilitated transits between Oct. 22 and 24, compared with a 2025 average of about 138 vessels per day, and estimated that roughly 492 ships were waiting outside the strait as of Oct. 25, gCaptain reported.

Iran’s blacklist and competing claims of control
Iran’s Persian Gulf Strait Authority, an Iranian government body, added two vessels to its non-compliance list over the weekend, bringing it to 123 ships, according to Seatrade. The additions were the Liberian-flagged supertanker Senegal Prosperity, which was hit by three projectiles on Aug. 31 while leaving the strait, and the Panama-flagged LPG tanker Sea Soar.
Iran’s armed forces chief of staff, Ali Abdollahi, said Monday that the Islamic Revolutionary Guard Corps had “full control and oversight” of the Persian Gulf coast, its islands and the strait, Iran International reported. That is a claim by a party to the conflict and has not been independently confirmed. U.S. Central Command (CENTCOM) gave a competing account on Sunday. It said more than 3,000 commercial vessels had transited the strait with U.S. support over six months and that Gulf states had exported more than 1.5 billion barrels of oil since June, Al Jazeera reported. CENTCOM commander Adm. Brad Cooper said the main transit routes were clear of Iranian mines. Both accounts come from parties to the conflict.
Diplomacy and oil markets
Iran’s ambassador to Pakistan said Saturday that Tehran was still willing to resume talks under a Pakistan-brokered interim agreement from June and had offered, through Islamabad, to reopen the strait if Washington lifted its naval blockade of Iranian ports, according to Iran International. Washington has not accepted that offer. Oil traders have been weighing those signals against the steady drumbeat of attacks, as we reported when oil prices fell more than 6% on Iran diplomacy. For American drivers and New England heating-oil customers, any new disruption in the strait can feed straight into prices.
