United States President Donald Trump warned Iran during an interview with Fox News on September 20 that failure to reach an agreement with Washington could result in severe economic consequences or action against Iran's leadership. Trump presented the alternatives as continued economic pressure or more direct action against Tehran. The remarks came amid ongoing confrontation between the two countries and American enforcement of restrictions on Iranian commercial shipping. The supplied article did not identify a new agreement, provide a negotiating timetable, or establish that the threatened measures had been implemented.

Iran's military warned that regional states supporting a potential new United States attack against Iran would be considered parties to the conflict. In a statement reported by the semi-official Tasnim news agency, Iran's Khatam al-Anbia Central Headquarters said its intelligence indicated that the United States and its allies were preparing another large-scale strike. The headquarters threatened sustained attacks against American positions and interests in the region if Washington launched an attack. The warning was reported on September 21, following related American statements on September 20. The alleged preparations were not independently corroborated in the supplied article.

United States Central Command announced on September 20 that American forces had redirected 109 commercial vessels since the beginning of its maritime enforcement campaign against Iran. CENTCOM said the operations were intended to ensure compliance with restrictions on commercial shipping linked to Iran. The announcement came amid a United States naval blockade of Iranian ports that the supplied article said had been maintained since mid-July. Iran has disputed Washington's account of control over the Strait of Hormuz. The report did not identify the individual vessels or provide independent confirmation of the cumulative figure.

The same report notes that on September 7, 2026, Tehran announced that an agreement with Muscat on a new corridor in the Strait of Hormuz would be signed within days. The article adds that shipping data through September showed a sharp decline in vessel traffic compared with levels before the war between the United States, Israel and Iran that began February 28, 2026, underscoring continued disruption despite diplomatic contacts.

Iran announced on 12 July 2026, according to Anadolu Agency, that it was closing the Strait of Hormuz again after the United States resumed attacks on 8 July. Authorities in Tehran threatened to target ships using routes other than those they designated or crossing the strait without permission; the source does not give the exact date of the threat. It does not explain how the closure operates, its effect on shipping or international reactions. The strait is one of the world's most important routes for energy and goods, according to Anadolu Agency.

The United States resumed its attacks on 8 July 2026, according to Anadolu Agency, and Iran announced the closure of the Strait of Hormuz again on 12 July. The source does not identify the targets, locations or losses of the attacks, nor the immediate reasons for the resumption, and only mentions them in the context of the war that began in February and the collapse of negotiations.

Washington and Tehran signed a memorandum of understanding on 18 June 2026, according to Anadolu Agency, and began negotiations, but the talks collapsed over disagreements on navigation in the Strait of Hormuz, one of the world's most important routes for energy and goods. The source does not state the memorandum's content, the signing location, any mediators or the date the talks collapsed. The US resumed attacks on 8 July, according to the same source, and Iran then announced the strait's closure again. No further detail on the negotiating parties or the points of dispute is given.

The United States and Israel began a war on Iran on 28 February 2026, according to Anadolu Agency, and Tehran responded with attacks on Israel and on US facilities in Arab states, some of them leading oil and gas producers. The source does not identify the locations of the initial strikes, the names of the affected Arab countries or the scale of losses, and gives no account of the later course of the war beyond negotiations and the closure of the Strait of Hormuz. Anadolu cited the event as background to its report on the Hormuz tanker incident.
