Reports indicate that an Iran-linked cyberattack last month disrupted a small UK gas power plant for four days, though the specific facility remains unnamed. Despite this incident, government documents confirm that mandatory cybersecurity standards for the sector will not be implemented until the end of 2030, a timeline that critics have described as a significant national security risk.

Washington Institute fellows are evaluating reported responses from Iranian-aligned groups, including Hezbollah and the Houthis, to current hostilities. The analysis also considers potential countermeasures by the U.S. administration and allies, citing a history of foreign terrorist plots attributed to Iran.

Iran and Oman are still working on the details of an agreement on the Strait of Hormuz, a senior Iranian source said on Wednesday, after Iran’s Revolutionary Guards said the two countries had agreed how to share the waterway and its revenues. The elite force’s spokesperson, echoing Tehran’s official stance, also said the strait would not open unless the United States met Tehran’s conditions under an interim ceasefire agreement that was struck in June before unravelling.

Those conditions include an end to the US blockade on Iranian ports, compensation and removal of sanctions. Iran and Oman have held on-and-off talks for weeks about controlling traffic through the strait, which handled one-fifth of global oil and liquefied natural gas shipments before the war began in February.

Most shipping has since been shut down, driving global energy prices higher, as Tehran and Washington have tried to assert control over the channel, imposing separate blockades. “An agreement with Oman over the Strait of Hormuz has not been finalised,” the senior Iranian source said, adding that the talks were continuing on the details of an accord.

A spokesperson for Iran’s Islamic Revolutionary Guard Corps (IRGC) said Iran and Oman had reached an agreement on their shares of the territory and revenues. “The Strait of Hormuz belongs to Iran and the country of Oman. We have been in negotiations with Oman for about a month, and we have reached results that are acceptable to both sides,” Hossein Mohebbi said in comments published by Iranian state media.

“In these negotiations, agreements have been reached regarding the share of each country in the waters of the Strait and the share of Iran and Oman in its revenues,” he added. It was not immediately clear at what stage of the negotiations the agreements had been reached.

Iran had said earlier this month that a deal on the strait was close. Following talks on Tuesday between Iran and Oman, Omani foreign minister Badr Albusaidi said he was “hopeful we will soon announce a temporary corridor for the Strait of Hormuz and practical arrangements to restore safe navigation”.

US president Donald Trump has warned Oman against co-operating with Iran, telling Fox News on August 17: “If Oman gets in the way, we’ll bomb the shit out of them.” The IRGC accused the US of seeking to obstruct Iran’s negotiations with Oman and said this had caused an agreement to be delayed.

“If the United States stops obstructing and returns to the agreement, we can open the Strait of Hormuz within the framework of the agreement reached. If the United States does not accept our conditions, the Strait of Hormuz will not be opened under any circumstances,” Mr Mohebbi said.

Though active hostilities between the US and Iran have largely subsided in recent weeks, diplomatic efforts to reach a peace deal have stalled, and continuing attacks on ships mean passage through the Strait of Hormuz remains perilous. Iran announced a blacklist on Sunday of 45 ships in an apparent effort to stop ship-to-ship transfers used by Gulf energy producers to evade the Iranian blockade.

Some companies plan to stop using vessels added to the blacklist, sources said. In an effort to tighten pressure on Iran’s economy, the US has threatened to punish countries that continue to do business with Iran, but said it would not impose penalties immediately.

The sanctions did not feature Chinese financial institutions suspected of facilitating oil exports from Iran that the US blockade has cut. Iran denounced the US effort to isolate its economy as an act of “gross lawlessness”, expressing confidence that many countries would not join the pressure campaign.

Oil prices fell for a third day, dropping more than 1.5pc, following signs of renewed efforts to seek a mediated end to the war that began on February 28 with US and Israeli strikes on Iran. Secretary of state Marco Rubio told allies that the US did not expect to launch new strikes against Iran for now, and would instead focus on other means of pressure, Axios reported on Tuesday.

US public approval of the war has fallen to its lowest level since the conflict’s early days, and Mr Trump’s popularity is likewise at a record low ahead of congressional elections in November, according to Reuters/Ipsos polling. Thousands of people have died in the conflict, most of them in Iran and Lebanon, while the U.

S. and Israel have degraded much of Iran’s conventional military capacity. The exact state of its nuclear programme, which the US and Israel aim to dismantle, remains unknown. Iranian army spokesman brigadier general Mohammad Akrami-Nia said new equipment had been delivered to combat units and fighting against two technologically advanced militaries had provided Iran’s forces with significant battlefield experience, according to comments carried on Wednesday by Iran’s Mehr News.
