Yesterday, 15 November, the Joint Terrorism Analysis Centre (JTAC) changed the UK national terrorism threat level from Substantial to Severe. This means that a terrorist attack is highly likely. The threat level was last at Severe from November 2020 to February 2021.
The decision to change the UK terrorism threat level is taken by JTAC independently of Ministers. JTAC keep the threat level under constant review based on the very latest intelligence and analysis of internal and external factors which drive the threat.
The public should remain alert, but not alarmed, and report any concerns they may have to the Police.
The Government, Police and intelligence agencies will continue to work tirelessly to address the threat posed by terrorism in all its forms.
