Iran says it will declare an exclusion zone

September 7, 2026

Iran says a prohibited zone outside the Strait of Hormuz will be announced within days, a day after U.S. strikes on three tankers linked to the Revolutionary Guards.

The Strait of Hormuz, a waterway that once moved a fifth of the world's oil, lies at the heart of a six-month war between Iran and the United States, whose July truce ended when vessels there came under attack.

Key facts

AP News reports that Mohsen Rezaei, the new head of Iran's Supreme National Security Council, told the state broadcaster Tehran plans an exclusion zone outside the Strait of Hormuz aimed at vessels it believes are trying to transit the waterway. The Straits Times carries Rezaei's wording: the zone begins at the U.S. Navy blockade line, reaches into the Persian Gulf, and any ship entering it goes on Iran's sanctions list. PBS, NBC News and Fortune carry the same sequence of events, with the announcement landing a day after U.S. forces struck three oil tankers in reply to Iranian ballistic missiles fired at American warships. Reuters ties the announcement to a restricted zone Tehran plans to name in the coming days, and Al Jazeera's live coverage carries the Hormuz route alongside the fighting in Lebanon. AP News also reports that state-run media in Tehran placed a U.S. vessel inside an area Iran calls restricted, and that Capt. Tim Hawkins, a U.S. Central Command spokesperson, called that account “a total lie.”

The rhetoric around the zone is corroborated across the set. AP News reports that Iran's parliament speaker and chief negotiator, Mohammad Bagher Qalibaf, said the era of proportionate responses is over and Iran's retaliation will be “faster, heavier and more painful,” and The Straits Times carries his promise of a faster, more intense and more painful response to any aggression, delivered in a speech on state media. The Straits Times reports that CENTCOM said on Sept 5 that Iran had fired unsuccessfully at an aircraft carrier and a destroyer, and that the U.S. then hit three tankers it linked to the Revolutionary Guards. NBC News reports the economic half of the picture: Energy Secretary Chris Wright put average flows through the strait at 9 million barrels of oil a day, an estimate NBC News says appeared to exceed average flows over the past 28 days according to TankerTrackers.com. PBS reports Rezaei's claim to state TV that Iran sells one million to one and a half million barrels daily, as if trade were continuing as usual.

The wider war frames all of it. NBC News and PBS report that the memorandum of understanding the U.S. and Iran signed in mid-June came apart within days, that nuclear talks collapsed with it, and that Washington now pairs military responses in the strait with sanctions on foreign financial institutions handling Iranian money. AP News and Fortune report Israeli strikes in southern Lebanon that killed seven people and leveled an empty hospital, per Lebanon's Health Ministry, with two of the dead in Arabsalim and two more in Nabatiyeh al-Fawqa. What is settled is the Iranian announcement, the strikes that preceded it, and the collapse of the June understanding. The count of Palestinians killed in Gaza since the October ceasefire is where the accounts part: one puts the figure at least 1,344, another does not hold to that number.

A relative, Mustafa Quzghat, said: “We are witnessing a painful, heartbreaking scene.”

The open toll is the Palestinians killed in Gaza since the October ceasefire, where the figures do not line up between the accounts.
