UK National Terrorism Threat Level Raised To SEVERE
Published date: 01 May 2026
The Joint Terrorism Analysis Centre (JTAC) has raised the UK National Threat Level from SUBSTANTIAL, meaning a terrorist attack is likely, to SEVERE, meaning a terrorist attack is highly likely.
This change follows the stabbings in Golders Green on 29 April, although it is not solely a result of that attack. The UK has been experiencing a gradual increase in terrorist threats for some time. This has been driven by a rise in both Islamist and Extreme Right-Wing terrorist threat from individuals and small groups in the UK.
The current terrorist threat is characterised by:
A significant volume, breadth and complexity of terrorist incidents and cases across various ideologies, including attack planning, extremist travel intent, and online and offline radicalisation.
Whilst Islamist Terrorism remains the primary threat to the UK, Extreme Right-Wing Terrorism (ERWT) has been on a steadily rising trajectory.
An elevated threat to Jewish and Israeli individuals and institutions, in the context of the conflict in the Middle East, evident in recent incidents in the UK and overseas.* *
While the UK National Threat Level set independently by JTAC reflects the terrorist threat in the UK, we are also seeing a sustained and significant tempo of State-linked threats including to Jewish and Israeli individuals and institutions.
