The US and Israel have launched what President Donald Trump has described as "major combat operations" to try to bring about the end of the Iranian regime.

In this bonus episode, Roland and Venetia look at what we know so far - from Trump’s speech to strikes across the Middle East - and what might happen next, while Henry Bodkin, The Telegraph’s Jerusalem correspondent, reports from on the ground in Israel amid air raid sirens around the country.

Plus, Roland speaks to Jonathan Hackett, a 20-year US Marine Corps veteran and special operations capabilities specialist, as well as the author of Iran's Shadow Weapons: Covert Action, Intelligence Operations and Unconventional Warfare. Their conversation - which was recorded shortly before the attack began - covers how Ayatollah Ali Khamenei was offered an escape route but refused to take it, the state of the IRGC and why regime change in Iran will be so difficult.
