Russia says it has detained a former guard at the British Embassy in Moscow, alleging he took part in an alleged Ukrainian operation. According to Russia’s claims, the person was involved in collecting information as part of preparations for what Russia calls a “false-flag” attack targeting British diplomatic staff.

The reports state that the Russian agency frames the alleged activity as part of a wider Ukrainian plan. However, the available excerpts do not include a response from the individual detained, the British government, or independent verification of the allegations. As a result, the scope and evidence behind Russia’s account are not established in the provided material.

Across the sources, the central point of agreement is the Russian allegation: detention of a former embassy guard and a claim that data collection was intended to enable an attack on British diplomats under a false-flag narrative.
