UK Raises Terrorism Threat Level to Severe

The UK raised its national terrorism threat level to 'severe' on Friday, signaling that an attack is highly likely within the next six months. The Joint Terrorism Analysis Centre (Jtac), part of MI5, made the assessment amid a gradual increase in terrorist threats.

MI5 stated the UK has been experiencing this rise for some time, driven by both Islamist and extreme right-wing threats from individuals and small groups.

The US embassy in London issued a security alert on Friday, warning Americans that an attack on the UK is highly likely. The embassy advised US citizens to remain alert in public places, including schools, hospitals, churches, tourist hotspots, and transport hubs.

It also recommended varying travel routes and times to reduce predictability and staying away from schools, churches, tourist locations, and transportation hubs.

The raised threat level follows the stabbing of two Jewish men in the Golders Green area of London on Wednesday. MI5 noted threats in particular to Jewish and Israeli individuals and institutions in the context of the conflict in the Middle East. Last week, the Finchley Reform Synagogue in north London was targeted, and an attack occurred on the Kenton United Synagogue in Harrow.

Jtac states that Islamist terrorism remains the primary threat to the UK, while extreme right-wing terrorism is steadily rising. The US embassy warning is based on assessments by Jtac. 'Severe' is the second-highest level on Jtac's five-point scale, meaning a terrorist incident is likely.

The UK's threat level was last raised to severe in 2021, when Conservative MP Sir David Amess was murdered by an Islamist in Essex and a bomb was set off outside Liverpool Women's Hospital by an asylum seeker. The threat level was downgraded to 'substantial' in February 2022. The increase in threat level follows a rise in Islamist and extreme right-wing ideology in the UK.

Counter terror police arrested 8 people across England over an alleged plot to commit arson attacks. UK police charged a man over the stabbing of two Jewish men in London. The US embassy issued a second security notice in the UK in the last few weeks, noting recent attacks and threats targeting Jewish and American institutions.

Metropolitan Police Commissioner Sir Mark Rowley urged Britons to be alert but not alarmed. He stated he was concerned about the scale of upcoming protests in London.

“Be alert, but don’t be alarmed." — Metropolitan Police Commissioner Sir Mark Rowley The Prime Minister condemned the use of the pro-Palestine phrase 'globalise the intifada'. The American Jewish Committee confirms the phrase means aggressive resistance against Israel and those who support Israel. The UK government recognized Palestine in 2025.”

“If you are on a march or a protest where people are chanting: 'globalise the intifada,' you do have to stop and ask yourself: 'Why am I not calling this out? Why am I on a march where this is the chant?'" — The Prime Minister The changed threat level also followed after the stabbing of two Jewish men in the Golders Green area of London on Wednesday, although it is not solely a result of that attack. The US embassy issued the security alert on Thursday night. The UK's threat level was raised to 'severe' on Thursday.”
