The head of Britain's domestic spy agency on Tuesday accused Russian military intelligence of being on a "sustained mission" to cause mayhem in Britain and Europe.
The spy chief said the agency was having to deal with a "dizzying range" of beliefs and ideologies, citing risks posed by Russia, Iran, China and others.
McCallum said the number of state threat investigations MI5 is running had jumped 48% in the last year.
He said the GRU — Russian military intelligence — in particular was on "a sustained mission to generate mayhem on British and European streets: we've seen arson, sabotage and more."
"This goes well beyond all historical precedent – and has put a big dent in the Russian intelligence services' ability to cause damage in the West," he added.
