A senior British intelligence official has issued a stark warning that a terrorist attack on the scale of 9/11 could already be in development, suggesting current surveillance efforts may have missed critical early signs. The alert highlights concerns over potential gaps in counterterrorism strategies, raising questions about whether existing measures are sufficient to detect emerging threats. Authorities are reportedly assessing whether new tactics or intelligence-sharing approaches are needed to prevent such an attack. The statement underscores the persistent challenge of anticipating and disrupting sophisticated plots before they materialize.
