AI and Terrorism Incident Tracker, June 2026
Self-radicalisation and attack planning
Lone individuals, largely in the West, whose intent was shaped or reinforced by consumer AI tools, or who used them to prepare violence. This is a product-safety and prevention challenge: the response sits chiefly with AI developers’ safeguards, alongside early detection.
Matthew Livelsberger
Deceased2025 · United States
Las Vegas police publicly described this as the first case on US soil in which ChatGPT queries were used to help plan an explosive device detonated outside the Trump International Hotel after Livelsberger took his own life, while OpenAI said the model had returned only publicly available information with warnings.
Jaswant Singh Chail
Convicted2023 · United Kingdom
He exchanged thousands of messages with a Replika chatbot companion that validated his stated intent before he entered the grounds of Windsor Castle with a loaded crossbow intending to kill Queen Elizabeth II, and was sentenced to nine years for treason in remarks that address the chatbot exchanges directly.
Organised use by terrorist groups
Established terrorist groups adopting AI as an operational and propaganda capability. This is a capability-diffusion challenge: the response sits with model access controls, repository and hosting policy, and counter-terrorism enforcement.
Pro-Islamic State propaganda network (Spain)
Group activity2024 · Spain
Spain's Interior Ministry said a media operative arrested near Barcelona in July 2024, part of a nine-arrest sweep against pro-Islamic State online propaganda, produced jihadist content using specialised editing applications powered by artificial intelligence, and was remanded in custody.
Islamic State supporter media network (News Harvest)
Group activity2024 · Transnational
Pro-Islamic State supporter networks, distinct from the group's official media arm, ran an AI-generated news-anchor programme called News Harvest from March 2024, repackaging official IS claims as broadcast-style bulletins within days of the Crocus City Hall attack.
Boko Haram (ISWAP and JAS factions)
Group activity2024 · Nigeria and the Lake Chad Basin
A University of Cambridge study based on interviews with former members reports that both Boko Haram factions used mainstream Western and Chinese chatbots to support attack planning and weapons work between 2023 and 2025.
Compiled from public court records, official reports and press reporting, and from Tech Against Terrorism’s CT Casebook, a continuously updated corpus of counter-terrorism cases. Public access to the Casebook is forthcoming. Headline figures from the AI and Terrorism Incident Tracker (June 2026).
