Key points
- Qatar's Foreign Ministry said on 27 October that Iran should stop threats against Arab Gulf states and open the Strait of Hormuz to show good intentions.
- Iran's Strait Authority said all vessels of South Korean firm Sinokor would face "legal action" from 1 November, after the highest number of crossing violations in three months.
- Tehran has restricted Hormuz transit since US-Israeli airstrikes on 28 February; the US imposed a naval blockade on Iran-linked ships in response.
- Trump said on 24 October that a new strike could come "maybe tomorrow", while also leaving a deal open and pledging no attack before the 3 November US midterms.
Qatar, one of the mediators trying to calm the confrontation between Washington and Tehran, has told Iran it must show good intentions if mediation is to succeed. A spokesperson for the Qatari Foreign Ministry told a press briefing on Tuesday that Iran should stop threats against Arab Gulf states and open the Strait of Hormuz, the strategic waterway at the centre of the dispute. Qatar, along with Pakistan, has been mediating between Washington and Tehran in an effort to end the US-Israeli war on Iran that has disrupted global shipping and oil supplies, in coordination with the United States. A Qatari delegation visited Tehran earlier in the week, and on Monday, top officials from Saudi Arabia, Turkey and Pakistan met Iranian officials in Tehran in an effort to de-escalate the conflict.
The mediation has not stopped Tehran from tightening its grip on the strait. Iran's Persian Gulf Strait Authority, a body set up by Tehran to manage passage requests in the Strait of Hormuz, said on Tuesday that all vessels belonging to South Korean shipping company Sinokor would face "legal action" starting on 1 November. The authority said on X that Sinokor vessels had committed the highest number of crossing violations in the strait over the past three months, and that "appropriate actions" had been taken against at least seven of them. Sinokor did not immediately comment. Ships owned by Sinokor were previously included on a list issued by Iran in August of 45 tankers that it said had broken its rules for crossing the Strait of Hormuz.

The strait at the centre
Tehran has sought to tighten its grip on the strategic waterway by attacking shipping there since the US and Israeli airstrikes on Iran on 28 February. It has restricted transit to try to gain leverage over Washington, while disrupting oil flows from Arab Gulf oil producers, especially to their customers in Asia. In response to Iranian attacks, the United States imposed a naval blockade against ships linked to Iran in the strait. While the blockade has all but choked off Iranian exports, Gulf producers have adapted to attacks on shipping by relying on so-called dark transits — switching off tankers' tracking systems to evade detection — to protect the oil flows that underpin their economies.
Strike warning and undersea cables
The warning from Washington still hangs over the talks. President Donald Trump said at a campaign rally in Florida on Friday that the United States "may do another little Epic Fury" — Epic Fury is the name of the American-Israeli operation against Iran launched at the end of February — or Iran will agree to terms. A day later, speaking to reporters in Florida after early voting, he put a timeframe on it for the first time: "We're thinking about doing it, and maybe tomorrow." He followed up at once: "Do you really think I'm going to tell you whether I'll do it?" His goal, he says, is to stop Iran from ever developing a nuclear weapon, and he left a deal open at the same time: "They want to make a deal, but the problem is, will they hold the deal?" He later wrote on Truth Social that the United States would not attack Iran before the midterm elections on 3 November, saying: "We are having productive discussions with the Islamic Republic of Iran." Iranian security officials, meanwhile, have told Reuters that Tehran has drawn up detailed plans to attack Gulf undersea cables if the United States and Israel attack again.
What happens next
The next hard date is 1 November, when Iran says its "legal action" against Sinokor vessels begins — a test of whether Tehran's strait rules are enforced against a major shipping line or left as a threat. Mediation continues, with Qatar pressing publicly for goodwill gestures and Gulf capitals watching whether the strait stays open. No breakthrough has been announced, and neither side has stepped back. Europe Unfolded will report what the mediators and the shipping lines do next, not what either side threatens.
