On 18 September 2026 the Russian foreign ministry summoned the UK chargé d'affaires over weapons supplies to Ukraine and said British military facilities in Ukraine used for strikes on Russia are legitimate targets, as reported by Al Jazeera and TASS.
Resolves on the same class of Russian government statement reported by Al Jazeera, in the window from 8 to 25 September 2026 inclusive. Repetition of an earlier statement by the same official counts only if it is issued in the window. If that source has not published in time, BBC News and Reuters settle it.
Each of four British firsts since 2023 drew a Russian threat. We looked at every time since 2023 that Britain was the first Western country to take a new step in military support for Ukraine. Each time, Russia publicly threatened Britain by name within 14 days. None of the four was followed by a military attack on British territory.
