The strait remains largely closed by Iran and the US blockade of Iranian ports continues; Iran calls the US reply to its seven conditions insufficient while saying it is still reviewing it. Ships are struck nearly every day, and the Houthi attacks on Riyadh's airport, 12 dead on 10 October by Saudi count, have widened the war.

The United States and Israel strike Iran across at least 17 provinces; a US official tells Fox News of nearly 900 strikes in the first 12 hours and the IDF says 500 targets. President Trump confirms Supreme Leader Khamenei is killed. Iran fires missiles and drones at US bases in Bahrain, the UAE, Kuwait, Qatar and Jordan and at Israel. Commercial traffic in the strait drops about 70 percent by MarineTraffic's count; no ship is attacked that day.

An IRGC adviser says on state television on 2 March that the strait is closed and any ship attempting to cross will be attacked. Oil and gas prices rise; QatarEnergy is reported to have halted LNG production after attacks on facilities.

A two-week US-Iran ceasefire took effect on 7 April, with reopening the strait the main US condition. Delegations led by Vice President Vance and by Iran's parliament speaker Ghalibaf and Foreign Minister Araghchi gather in Islamabad under Pakistani mediation. Iran has restricted passage with permissions and fees; Lloyd's List counts more than 600 vessels stuck in the Gulf, against 120 to 150 daily transits before the war.

The US blockade of all ships entering or leaving Iranian ports takes effect on 13 April, enforced in the Gulf of Oman and the Arabian Sea east of the strait. The USS George H.W. Bush carrier group, which left Naval Station Norfolk on 31 March, is en route around Africa; at least 27 Navy vessels are in or arriving in the region.

President Trump and President Pezeshkian sign the Islamabad memorandum electronically on the evening of 17 June; Pakistani mediators announce it is in force. Iran is to reopen the strait and the US to begin lifting its blockade, with 60 days of talks on a final agreement. Iran's Supreme National Security Council says traffic will increase gradually and no fees will be charged for 60 days.

CENTCOM lifts the blockade on all maritime traffic entering and leaving Iranian ports and says all enforcement has ceased, with ships remaining in the area. Vice President Vance says 12.5 million barrels passed through the strait the day before and that the Navy let more than a dozen ships pass.

Three ships are struck near Oman on 7 July; CENTCOM names them as the Al Rekayyat, Wedyan and Cyprus Prosperity, and US forces hit more than 80 Iranian targets including 60 IRGC small boats. At the NATO summit in Turkey, President Trump says the ceasefire is over. Ghalibaf accuses the US of breaching the memorandum by reinstating oil sanctions.

Iran declares the strait closed. JMIC says the southern route remains open and has been widened for two-way traffic, keeps the threat level at severe, warns of a mine danger zone inside the traffic separation scheme and of hostile radio calls from Iranian naval forces, and says no authority regulates passage or charges fees on the corridor.

The blockade of vessels to and from Iranian ports and coastal areas resumes at 4 p.m. ET, announced the day before. CENTCOM begins a seven-hour wave of strikes on missile and drone sites, naval capabilities and coastal defences. President Trump drops a proposed 20 percent US fee on cargo through the strait in favour of Gulf investment deals.

The Congressional Research Service updates its Hormuz report: in 2025 about 25 percent of the world's seaborne crude and products trade and 19 percent of LNG passed through the strait; the blockade is reimposed; Iranian leaders point to the memorandum as granting them the right to administer the strait; most ships either accede to Iranian demands or do not transit.

The memorandum's 60-day window expires without direct talks or an extension. Each side says the other broke it. Kpler counts five crossings on the Saturday and none on the Sunday.

Foreign Minister Araghchi presents a seven-day plan at the UN General Assembly: the US releases frozen funds, lifts oil sanctions and ends the blockade within four or five days, and final-deal talks begin by day seven. President Trump says the proposal would not be acceptable. Araghchi says Iran will not back down on its conditions.

UKMTO's weekly report: traffic through the strait remains about 75 percent below pre-conflict levels; 31 of 48 projectile strikes reported since 6 July were on the southern Omani route; 124 outbound and 123 inbound transits in the seven days to 2 October.

Parliament speaker Qalibaf says the strait will not open until Iran's seven conditions based on the Islamabad memorandum are met, after the US replied to Iran's plan through Qatari intermediaries. Spokesman Baghaei says the dispute is now about the strait, not nuclear matters, and denies offering inspections for sanctions relief. Reuters reports the gap is over sequencing.

CENTCOM redirects the 130th commercial vessel since 14 July. It says three ships that refused to comply have been disabled and 13 commercial vessels destroyed over 12 weeks. Admiral Brad Cooper says forces will act against any vessel trying to run the blockade. Mariners are told to monitor Notice to Mariners and use channel 16.

The USS George H.W. Bush, home port Naval Station Norfolk, arrives in Phuket, Thailand, after leaving the Arabian Sea without announcement, its first port call since 31 March. USS George Washington is the only carrier left in the region; USS Theodore Roosevelt left San Diego on 27 September to relieve or join it.

The EIA's weekly survey puts US regular gasoline at $4.354 a gallon on 5 October, down 11 cents on the week; Lower Atlantic regular $3.959; diesel $6.199. Its October outlook assumes Middle East flows stay constrained through the fourth quarter and forecasts Brent at $105 for the quarter.

Saudi Arabia's GACA says attacks on Abha airport on 6 October and Riyadh's King Khalid airport on 7 October killed three residents and injured 36. The Saudi-led coalition says it intercepted a ballistic missile north of Riyadh and destroyed a launch platform in Sanaa. The Houthis claim the attacks. The US embassy in Riyadh issues a security alert.

UKMTO reports a tanker struck by several projectiles 94 km north of Madinat ash Shamal, Qatar, on 7 October, with casualties reported but not counted. UKMTO said on 6 October there had been nine attacks on tankers in the strait so far in October. Kpler's provisional data show Middle East crude exports back near pre-war levels.

GACA says two attacks on King Khalid airport on 8 October killed three Saudi citizens, including a pilot named by Saudia as Captain Hamoud Ali Alkalthami, and wounded several others; a Saudia aircraft was damaged. Operations resume. The Houthis say they fired a ballistic missile at the airport. The coalition says it destroyed three launch platforms.

USNI News: the IMO counts nine ships struck between 1 and 6 October, and UKMTO two more on 7 and 9 October. Lloyd's List counts 12 attacks in the week to 7 October, the most of the war, and 143 transits in the same week. CENTCOM has not listed the 13 ships it says it destroyed.

Iran's Revolutionary Guards say they struck the LPG carrier NV Sunshine on what they call an illegal route south of the strait and that Iranian forces have taken over the strait's administration. President Pezeshkian, at a summit in Turkmenistan, says talks under force are coercion. AFP notes the US has not struck Iran since 1 September.

CENTCOM says 133 commercial vessels have been redirected as of 9 October to ensure compliance with the blockade, which it calls ironclad.

The Kremlin says President Putin relayed Iran's position on a resolution to President Trump in their 9 October call. Trump says the blockade will remain in full force and that there will be no attack on Iran before the 3 November elections; he says the US may join Saudi strikes on the Houthis. Brent trades near $105. A new attack on Riyadh's airport on Saturday injures several people; GACA suspends operations and the US mission tells citizens to avoid the airport.

CENTCOM says a fighter jet disabled the Panama-flagged cargo vessel Ocean Molica in the Gulf of Oman after it ignored repeated warnings and tried to run the blockade, having left an Iranian port; the crew was unharmed. Its running count: four vessels disabled, 135 turned around and 10 IRGC-linked tankers destroyed since 14 July.

GACA puts Saturday's attack on King Khalid airport at 12 dead, among them a US citizen, and 309 wounded. The coalition calls it a war crime and says it will respond. The Houthis claim the attack on Sunday and warn travellers off Saudi airports. Trump says the US may join Saudi strikes on the Houthis. The US Mission tells citizens to avoid the airport. Riyadh's airport stays closed.

Iran's security chief Rezaei calls the US response to the seven conditions insufficient, says some were accepted and others remain unclear, and that Iran is no longer in the process of responding. Foreign Minister Araghchi tells his Saudi counterpart Iran is ready to help start dialogue between Riyadh and the Houthis.

UKMTO warning 164-26: an outbound tanker is struck on the port side by an unidentified projectile inside the strait; crew safe, authorities investigating. UKMTO also reports a tanker hit by a drone at the Sohar anchorage; Seatrade names it as the Petro Dolphin with two Indian seafarers missing. The IRGC Navy says a supertanker on an unauthorised route hit a mine on Saturday night.

A projectile strikes Terminal 4 at King Khalid airport on Sunday evening, killing a Pakistani resident and injuring 11, GACA says; the coalition says it intercepted a cruise missile nearby. GACA confirms an attack on King Fahd airport in Dammam the same evening. The Houthis claim both and strikes on two Aramco facilities. India says a citizen died of Saturday's injuries, making 13.

GACA extends the suspension of operations at Riyadh's airport; the coalition says drones and missiles are still being intercepted. Baghaei says Iran is still reviewing the US response and will reply through intermediaries. Brent reaches $106.19 by 1124 GMT, its highest since 29 September. Airlines cancel Saudi flights; the FAA tells US airlines to use caution over Saudi Arabia.

Mohsen Rezaei says the shuttle moving Gulf oil out of the strait is now an explicit Iranian target and calls it smuggling. Windward counts 31 daily transits in the last week of September against 138 before the war, and at least 15 ships believed targeted in October so far. The IRGC says it struck three supertankers over two days; UKMTO reports no attacks Monday and at least two projectiles hitting vessels Sunday.

Baghaei says Iran has reached an understanding with Oman on a temporary shipping route, with implementation details still being worked out. The coalition says it intercepted three drones north of Riyadh. Egypt's foreign minister tells Araghchi the Houthi attacks on Saudi Arabia have no justification.
