Russia threatens that it could launch attacks on British military targets "beyond the borders of Ukraine" if Ukraine continues to use British missiles.

Russia warned on Thursday that it could strike British military targets both inside and outside Ukraine, in response to Ukrainian attacks on targets within Russia using British long-range cruise missiles.

The warning, delivered by the spokesperson for the Russian Ministry of Foreign Affairs, Maria Zakharova, at a press conference, had been made previously but without such a forceful rhetoric or sense of urgency.

Western analysts stated that the severity of Moscow's warning reflects Russia's anger over Britain's decision - made public on Monday - to allow Kyiv access to classified technology to begin its own production of Storm Shadow cruise missiles, capable of launching deep strikes into Russian territory.
