Russian officials just piped up over MI5′s recent warning Moscow agents are looking to cause “mayhem” on British streets and wrote the claims off as “scare tactics”. On Tuesday, MI5′s director-general Ken McCallum claimed Vladimir Putin’s “henchmen” were looking to strike away from the battlefield “in the misguided hope of weakening Western resolve”.

MI5's Ken McCallum warns of Russian chaos, Iran plots, rising terror threats, and increasing youth radicalisation in the UK.

The head of Britain’s domestic security service said Russia’s military intelligence service was pursuing “dangerous actions conducted with increasing recklessness.”
