Quick Summary

On Tuesday at Thames House, MI5 chief Sir Ken McCallum warned of the potential for terrorists to misuse AI, particularly in developing bioweapons. He highlighted that while current terrorist groups lack access to advanced biological weapons, AI could change this dynamic by making sophisticated weaponry more accessible to less technically capable actors. McCallum also stressed the need for societal resilience against these threats and called on the British public to contribute to national security efforts.

Story summary

On October 13, 2026, Sir Ken McCallum, the head of MI5, delivered his annual speech at Thames House, warning about new threats to Britain's security. He highlighted the potential misuse of artificial intelligence (AI) by terrorists, which could enable them to create and weaponize bioweapons more easily than before. This poses a significant risk because even low-sophistication actors may gain capabilities in the AI era if proper guardrails are not enforced. McCallum noted that while terrorists have long sought chemical or biological weapons, advancements in AI technology make these threats more imminent. He also emphasized that Iran and Russia pose escalating hybrid warfare risks to Britain, with recent incidents such as a suspected Iranian plot against RAF Fairford being indicative of broader ambitions by Tehran to target military sites.

Why this leaning score
This article does not take a side on a contested political question, so it has no leaning score. That is an answer rather than a gap: a match report or a rescue can be warmly or critically written without being left or right, and scoring it anyway is how approval of a subject gets recorded as a political position.

Narrative

For the last 25 years I suppose, if you look at where al Qaida was in the 9/11 era, it has long been the case that many terrorists would dearly love to have some kind of capability around chemical or biological or radiological weaponry but that hasn’t been easy for them to achieve.
