Terrorism-related incidents recorded in November 2025 highlight an increasingly complex and fragmented threat environment, according to a new assessment from Pool Re’s threat analysis team. Drawing on recent incidents and newly released UK government data, the analysis shows how a mix of ideological, behavioral, and situational factors continues to shape the terrorism risk landscape in the UK.
A central focus of the assessment is new Home Office data released November 6 on referrals to the Prevent programme between April 2024 and March 2025. During that period, 8,778 individuals were referred – a 27 percent increase from the previous year and the highest total since records began in 2015. Of those referrals, 85 percent progressed to the Channel programme, up from 57 percent the year before, indicating a higher share of cases meeting the threshold for intervention.
The data also points to shifting referral patterns. The “no ideology” category accounted for the largest proportion of referrals at 56 percent, though these cases were less likely to be adopted by Channel. Referrals linked to a “fascination with extreme violence or mass casualty attacks” made up 5 percent of the total but rose sharply, increasing 240 percent between January and March 2025 compared to the previous quarter. Extreme Right-Wing concerns accounted for 21 percent of referrals, followed by Islamist extremism at 10 percent.
Young people continue to feature prominently, with individuals aged 11 to 15 representing 36 percent of referrals. Around one-third of cases involved at least one recorded mental health or neurodiversity condition, with autism spectrum disorder most commonly noted.
Alongside the Prevent data, Pool Re’s assessment identifies three enduring themes: individuals fascinated by extreme violence remain an ongoing concern; the threat from Foreign Terrorist Organizations, particularly Islamic State, persists; and publicly accessible locations continue to be priority targets for terrorist actors.
