Evidence

The claim originates entirely from a Russian FSB statement issued in September 2026, which announced the arrest of a former security guard at the British Embassy in Moscow accused of gathering intelligence on British diplomats for Ukraine. The FSB alleged that Ukrainian intelligence intended to use this information to stage a false-flag terrorist attack on British diplomats and blame Russia, with the goal of drawing the UK into direct conflict with Russia and securing more military aid for Kyiv. This FSB statement was reported widely by Russian state media (RT) and picked up by outlets such as The Moscow Times, TRT World, Al Jazeera (in the context of a similar prior FSB claim), and fringe/opinion sites like The Gateway Pundit and Aletho News, all of which simply relay the FSB's unverified allegations without independent corroboration. Neither the UK Embassy in Moscow nor the British Foreign Office has publicly confirmed any part of this story, and Kyiv has not substantively responded either, according to the reporting found. Notably, Ukraine's own Center for Countering Disinformation (reported via ua.news) explicitly labeled the FSB's statement a 'Russian fake,' arguing it may be an attempt by Moscow to preemptively shift blame for actions Russia itself might be planning. No fact-check from Reuters Fact Check, AFP Fact Check, Bellingcat, or EUvsDisinfo specifically addressing this claim could be located in the search results obtained.
