Iran's Hormuz permit authority has threatened legal action from 1 November against every ship of Sinokor, the South Korean shipping company whose ships carried nearly 40% of the crude leaving Hormuz in September; a shipowners' association says the listed ships are chartered, not Sinokor's own. The Mecca pact states met Iran's security chief in Tehran, Britain charged two men in the Fairford case and physical Brent climbed $13 in three sessions.
Iran is pressing Hormuz through Sinokor, its busiest commercial operator, rather than through warships alone.
Iran's Persian Gulf Strait Authority says every Sinokor vessel faces legal action from 1 November. Sinokor ships carried nearly 40% of September's Hormuz crude.
United KingdomUnited StatesIran's Hormuz permit office warned on 27 October that every ship of Sinokor Merchant Marine, a South Korean owner, faces legal action from 1 November. Sinokor ships moved nearly 40% of September's Hormuz crude.
The warning goes to insurers and cargo owners, not to the crews. Seoul's shipowners say the named ships are sub-chartered, so underwriters must now decide whose risk it is.

ChinaUnited StatesUnited Arab EmiratesThe naval arm of Iran's Revolutionary Guards said on 29 October that three tankers hit mines and burned within 24 hours. It said all three used the southern exit through Oman's waters.
Only one fire, near Khasab, has outside confirmation. Abandoned crews would leave casualty records, so this claim, unlike those of 22 October, can be tested.
The Houthis' spokesman says missiles hit Saudi Arabia's defence ministry in Riyadh and the Ras Tanura refinery. Saudi Civil Defence says two missiles over Riyadh were intercepted.
Houthi spokesman Yahya Saree said on 27 October that missiles hit Saudi Arabia's defence ministry in Riyadh and the Ras Tanura refinery. Saudi Civil Defence said two missiles over Riyadh were shot down.

Turkey's parliamentary foreign affairs committee approved the Mecca defence pact with the votes of the opposition CHP. A ruling-party official said a motion to station personnel in Saudi Arabia would follow.
FranceTürkiyeA Turkish parliamentary committee approved the Mecca defence pact with Saudi Arabia and Pakistan on 27 October. The opposition CHP (Republican People's Party) voted yes alongside the ruling bloc.
The pact binds Turkey only after a full plenary vote. A separate motion could then send Turkish air-defence crews to Saudi Arabia, though a minister says none is planned now.

A day later Guo condemned attacks on civilian airports after the Houthi claims against Saudi Arabia. Beijing buys oil from both Riyadh and Tehran, and now speaks up for Saudi sites too.

The US-led naval reporting cell called more deliberate attacks in Hormuz highly likely and warned of renewed mining, eight days after dismissing the Guards' mine claims.
United StatesThe Joint Maritime Information Center, a US-led naval reporting cell, rated the Hormuz threat severe on 25 October. About 492 ships sat waiting outside the strait that day.
The UN shipping agency counted 29 attacks in the first three weeks of October, the worst month since March. Unlike the Red Sea in 2024, Gulf loaders have no sea route around the danger.

The open-market dollar in Tehran touched 2,735,000 rials intraday on 27 October, the Tehran price tracker TGJU says.
On 27 October one US dollar briefly cost 2,735,000 rials on Tehran's open market, according to a Tehran price-tracking website. On 29 September it had cost 2.5 million.

Qatar-led mediators put new terms to Iran. An Iranian official said on 28 October that Doha brought ideas, not a proposal.
United Arab EmiratesQatar-led mediators brought new terms to Iran this week. On 28 October an Iranian official described what Doha carried as "ideas, not a proposal".
The wording keeps Tehran free to reject the terms without refusing an offer. Doha also runs Iran's indirect channel to Washington, alongside Pakistan, so the label matters.
Up at sea, sideways on land. The Sinokor notice takes effect on 1 November, and the first test is whether insurers keep covering the listed ships; the JMIC, which counts 156 confirmed incidents in the region since 1 March, already warns of renewed mining. The Houthi missiles at Riyadh were intercepted and the Ras Tanura claim is unconfirmed. The Wall Street Journal reported that Washington warned Gulf states of a possible short, intense renewal after the US midterms of 3 November 2026, two days after the notice bites.
