MI5 director general Ken McCallum used his annual threat assessment on Tuesday to warn that Iran and Russia are escalating hybrid campaigns against the UK. McCallum said Iran has made a “major shift” toward harder targets such as military sites, and said more than 50 people were arrested over Iran-linked operations in the past year. The Hill, Deutsche Welle and The Washington Times report a suspected plot against a US-run air base in September, which McCallum called “not unique.” McCallum also listed AI, terrorism and far-right anti-migrant threats among the risks facing Britain. Deutsche Welle reports that the investigation into the air base incident is ongoing.
