The UK's official terrorism threat level was raised to 'severe' on April 30, 2026, meaning authorities assess that a terror attack is highly likely within six months. The decision follows a stabbing attack in Golders Green where two Jewish men were injured; though not solely caused by that incident, it reflects a broader rise in Islamist and extreme right-wing threats from UK-based individuals and small groups. This is the highest threat level since November 2021. The suspect in the Golders Green attack had been flagged to the government's counter-extremism program in 2020 but his case was closed that same year.
