MOSCOW – Russian Foreign Ministry spokeswoman Maria Zakharova said on Thursday that Moscow will retaliate with strikes on British targets if British weapons are used by Ukraine to strike Russian territory.
Zakharova told reporters that British targets “on Ukraine’s territory and beyond its borders” could be hit in such a scenario.
She was repeating a warning that Moscow first issued earlier this month after British Foreign Secretary David Cameron said Ukraine had a right to use weapons provided by London to hit targets inside Russia.
Russia reacted with outrage to that remark and cited it as one of the reasons why it has opted to hold exercises this month to simulate the launch of tactical nuclear missiles. REUTERS

Well you ugly whore. Ukraine have used Storm Shadows on Crimea countless times, destroying everything from ships to command centres. Are you saying that Crimea is not russian, or are you just opening your big mouth to utter more empty threats?
China, Iran and North Korea will not support that new Russian rule. Countries that deliver weapons are not participants in war, period. And to threaten the most aggressive of European powers certainly isn’t a good idea. The Brits have shown time and again in history that they’re not the kind of people which back down to attempts at intimidation. ✊😠🇬🇧
Of course russia isn’t on the receiving end of Western aid, unlike in WW2, where the USSR was flooded with Western aid.
