Russia’s intelligence agency has been on a mission to generate “sustained mayhem on British and European streets”, the head of MI5 has said.
In a rare public speech, Ken McCallum warned that the UK was facing the most “complex and interconnected” threat it has ever seen.
MI5 has also responded to 20 Iran-backed plots since 2022, the director general said.
He said the complex mix of terror-related threats and threats from nation states meant that MI5 had “one hell of a job on its hands”.
