Iran–Gulf developments — 11 October 2026
The strait carried less and was struck more. After the war's heaviest week of strikes on tankers, Iran's Revolutionary Guard claimed one itself, for sailing an "unauthorised route", and said such ships will be pursued beyond Hormuz. Tracked transits fell to seven on 6 October, the fewest since July, and crude crossing the strait fell by more than a quarter in a week. The bypasses on the Gulf of Oman and the Red Sea took more. Central Command called the lanes open to ships that do not break US sanctions. No cover was found written, and no régime was agreed. In the south, planning became an offensive. On 4 October Yemen's Leadership Council announced operations to retake Houthi-held territory, under a Saudi-led air campaign. The Bab el-Mandeb shore is claimed by both sides and secured by neither. Attacks on Riyadh's airport killed three on 8 October and twelve on 10 October, by Saudi account. Tehran says it has revised its proposals. Nothing is in force.
The developments
Strikes on tankers continued through the window. On 5 October UKMTO warning 156-26 reported a tanker in the strait with damage and a fire in its engine room; security sources named the Liberia-flagged LIPSI. On 6 October the Panama-flagged On Peace was struck about nine nautical miles off Limah and set on fire. Oman's defence ministry evacuated ten crew to Khasab. India's foreign ministry said at least twelve of the nineteen were injured. UKMTO also reported a tanker struck north of Qatar with casualties on 7 October, and an LPG carrier struck west of Al-Jazira in the UAE on 9 October. On 9 October the Revolutionary Guard claimed it had set the "Sun Shine" ablaze for using an "unauthorised route" in the strait's southern section. It said action against "violating" vessels would no longer be limited to the strait, and that companies cooperating with the United States would be sanctioned and their ships targeted. Kpler counted seven commodity vessels through the strait on 6 October, the fewest since 23 July, against more than twenty on each of 4 and 5 October. Kpler put crude crossing the strait in the latest week at no less than 10.1 million barrels a day, down 27 per cent from the week before. It put exports from the Gulf of Oman coast and the Red Sea at 6.7 million, more than double pre-war. On 9 October Central Command said it had cleared mines from the main lanes and declared them open to vessels not violating US sanctions on Iran. On 10 October it said a US fighter had disabled a vessel leaving an Iranian port, the fourth disabled since the blockade began on 14 July.
Why it matters. The attribution layer moved. Through the strikes of late September no party claimed a ship, and the Strait Authority spoke only of a list. Now the Guard has claimed one in its own name and given a reason, a route Iran has not authorised. It has also stated a reach beyond the water it says it controls. That is a legal claim enforced unilaterally. No other riparian accepts it, and it is not a régime. The commercial effect showed within days. The recovery the module recorded a week ago was built on short state-company legs across the strait, and those legs carried less. Volume moved to the outlets outside it. Two blockades now run side by side. The United States stops ships leaving Iranian ports, and the Guard strikes ships using routes it has not authorised. Central Command's "open" is conditional on the first; it says nothing about the second. The item does not establish who fired on the vessels the Guard did not claim, or that the claimed "Sun Shine" is the carrier UKMTO placed off Al-Jazira.

On 4 October Rashad al-Alimi, chairman of Yemen's Presidential Leadership Council, announced operations to retake all remaining Houthi-held territory and Sanaa. On 5 October the government military said a "strategic offensive" on Sanaa had begun. The Saudi-led coalition's spokesman said the coalition was providing round-the-clock air support and air cover for the Bab el-Mandeb strait. By its own count, 100 jets took part and 324 "high-value" targets were destroyed. The coalition called the operation "Yemen Dawn"; other reporting renders it "Dawn of Yemen". Government forces said they controlled the strait's shore and Dhubab airport, and the government agency Saba reported Mokha taken. The Houthi movement denied losing any territory. On 10 October Yemeni military sources told AFP that forces were advancing near the strait but had not yet secured the waterway, and that Perim (Mayun) remained in Houthi hands. The coalition said it had destroyed more than 130 targets that day. Military sources on both sides put the dead at 63 in 24 hours. The US Secretary of State sided with Riyadh and the Yemeni government on 5 October.
Why it matters. A week ago the module recorded an offensive in planning and kept planning apart from a campaign. That line is crossed. A party announced the operation with a stated objective, and the coalition acknowledged an air campaign and named the strait as a task. It is the first time since the July blockade that the shore Saudi Arabia's Red Sea outlet depends on has been contested by force rather than absorbed. What is not established is the result. Every territorial claim is a party's, the movement denies them, and the government's own sources said on 10 October that the waterway was not secured. Nothing in the record shows passage through the strait changing in either direction. This is an operation on the shore, not a naval operation in the strait's approaches. The Bab el-Mandeb question's coalition-operation observable is not met by it. No Makkah Agreement act was found.
Late on 5 October the Houthi movement said it had targeted airports and military sites across southern Saudi Arabia, King Khalid International Airport in Riyadh and Aramco's Rabigh refinery. Riyadh did not confirm the Riyadh or Rabigh claims. Saudi Arabia's civil aviation authority said attacks on Jazan and Najran airports caused three minor injuries. On 8 October two attacks struck King Khalid International Airport, one on airport facilities and one on a Saudia aircraft with no passengers. The authority said three people were killed, among them a Saudia captain. The movement had claimed attacks on the airport earlier that week. On 10 October a further attack there led the authority to suspend operations. Saudi officials said that evening that at least twelve had been killed and 309 wounded, an American among the dead. The State Department blamed the movement, which had not claimed the attack. Asked whether the United States would join the campaign, the President said: "We may. We're gonna look at it." The Gulf Cooperation Council's Secretary-General condemned the 8 October attack on 9 October, saying Saudi security is part of the security of all member states. Qatar, Kuwait, Jordan, Egypt and the European Commission also condemned the attacks.
Why it matters. The front's reach was already established: fire at Riyadh in September, every Saudi account an interception. This window it caused deaths in the capital, at a civilian airport, twice in three days, as the offensive in Yemen got under way. The two attacks are recorded separately with their own sources. The second's toll comes from Saudi officials hours after the event, and its attribution comes from Washington, not the movement. Neither attack moves the standing arrangements the module tracks. The Gulf answer was a statement of shared security without a mechanism, and no signatory named the Makkah Agreement. The United States weighed joining, and that is not a strike. None of these sites is a published energy or base marker. They are recorded here, not in the activity series.

On 8 October President Pezeshkian told President Putin, at a meeting in Turkmenistan, that Iran and the United States had exchanged new proposals and that Iran had revised them: "Once they are finalized, we are supposed to sit down through the existing intermediaries." The Kremlin said on 10 October that Putin had relayed Iran's position on a peace deal to the US President in a call on 9 October. On 8 October the US President said the United States would not attack Iran before the 3 November elections. On 9 October he said Iran would either "give us everything" or cease to exist. The same day a Friday prayer leader said the strait stays closed until Iran's "seven conditions" are met.
Why it matters. The channel is still moving texts. A revision after the US feedback of 29 September keeps the exchange alive through the same intermediaries, and Moscow has added itself as a relay. Nothing has moved from signalling to implementation. There is no framework, no schedule and no text in force, and no reply with a date for a first step. The pledge not to strike before the elections is a statement of intent with an end date of its own. It is not an instrument, and the module records it as said.
