Multiple reports say a security expert has warned that Iran could recruit “sleeper agents” in Britain and position them to carry out terror attacks. The reports describe concerns that individuals could be motivated to target Jewish people, though specific operational details, timelines, or confirmed plots are not provided in the cited material. The warning is framed as an intelligence and counterterrorism risk assessment, suggesting that state-linked actors may use covert networks to plan or enable future violence. The reporting also emphasizes that such recruitment and clandestine activity are difficult to detect in advance, which is why analysts monitor threats from overseas actors. No outlet in the provided excerpts cites a specific incident, arrest, or specific evidence demonstrating an imminent attack. Instead, the focus is on the possibility of future-directed threats and the need for vigilance. The accounts therefore reflect a general warning about potential tactics rather than a confirmed, named plot.
