The UK's terror threat level has risen due to an increase in rightwing extremists considering attacks, particularly targeting immigration centers and asylum hotels, according to MI5 Director General Ken McCallum. He described this shift from radicalized sentiment to violence as the most significant trend in the agency's caseload over the past year.
McCallum noted that young people are especially susceptible to extreme rightwing terrorism, with MI5 investigating a radicalized 13-year-old. He also referenced a case from a year prior where a 16-year-old was sentenced for planning to firebomb a Muslim center.
Beyond domestic extremism, MI5 is tracking increased hostile activities from Iran, which is reportedly aiming for harder targets like military sites and has been targeting British Jewish communities with plots and arson. Russia remains a primary concern, labeled "aggressor number one" for its ongoing assassination plots, explosive threats, and cyber-attacks against the West. Moscow's past interference in the 2016 Brexit referendum via media and social media was also mentioned.
In response to emerging threats, MI5 is establishing a new AI threat assessment center to combat the potential misuse of artificial intelligence for creating bioweapons. McCallum also highlighted a worrying rise in violence directed at political figures and community groups.
