The UK is in shock after an Iran-linked Islamist group claimed yet another attack on Jews in London.

In the wake of the Golders Green stabbing attack, national security editor Rozina Sabur looks at what we know about the shadowy online group known as Harakat Ashab al-Yamin al-Islamia (HAYI) and its links to the Iranian regime.

Plus, as Donald Trump weighs whether to take further military action against Iran or in the Strait of Hormuz, Samuel Olsen, chief analyst at risk and intelligence firm Sibylline, explains that the conflict has further indebted the US to China. Why? Beijing’s near-total dominance of the supply chain of rare earths and critical minerals, which every bit of modern military kit requires. Trump’s upcoming visit to Beijing to meet Xi Jinping is likely to centre on this issue - as well as Taiwan.

Elsewhere, Venetia Rainey and Sophia Yan analyse what we learned from Secretary of Defence Pete Hegseth’s first under-oath testimony on the war and why the ceasefire seems to be holding everywhere apart from Iraq.

Highlights

• Why the US cannot rearm post-Iran war without China
• Rozina Sabur on the Iran-linked group claiming to be behind the Golders Green attack

From the Strait of Hormuz to Lebanon, the Iran war has seen the West’s foes adopt asymmetric warfare with growing efficacy.

Fresh off the boat from the Omani side of the Strait, Adrian Blomfield joins Venetia Rainey and Roland Oliphant. He explains how being out on the busy, misty and historic waterway helped him to understand why it is almost impossible for the US to counter Iran’s so-called “mosquito” fleet of fast boats.

Meanwhile, Jerusalem correspondent Henry Bodkin discusses the growing threat posed by Hezbollah as it adopts Ukrainian drone tactics to fight Israeli troops in southern Lebanon. He talks through a particularly worrying video showing the terror group flying a fibre-optic first-person view (FPV) drone at a medivac helicopter.

Plus, Venetia and Roland run through the latest updates from today, including Donald Trump’s new threat to Iran and bad signs from the Iranian economy.

Highlights:

• Adrian Blomfield on his trip to the Strait of Hormuz
• Henry Bodkin on the growing threat posed by Hezbollah as it adopts Ukrainian drone tactics

Iran’s regime is facing an existential crisis prompted by the US-Israeli war.

Despite taking a military battering and the economy being in ruins, Tehran refuses to surrender to Donald Trump. Historian Arash Azizi takes Roland Oliphant and Sophia Yan inside the clash between the regime establishment and the ultra-hardliners who fear their vision of the Islamic Republic will not survive peace.

He explains why the country’s powerful, IRGC-linked chief negotiator Mohammad Ghalibaf is increasingly being attacked in Iranian media and the dilemma facing the Islamic Republic as it looks to make a deal without surrendering the anti-American dogmatism that revolutionaries hold so dear.

Plus, senior foreign correspondent Adrian Blomfeld reports from the Strait of Hormuz and Sophia and Roland discuss the significance of the UAE pulling out of OPEC.

Highlights

• Arash Azizi on why Iran’s hardliners are a “bunch of losers with no power”
• How the Iranian regime is facing a choice between reform and destruction
