Russia on Friday accused six British diplomats of spying and announced it had stripped them of accreditation, a move that came as Western leaders were discussing whether to allow Ukraine to strike military targets deep inside Russia using long-range Western weapons.

       On a day when President Joe Biden and British Prime Minister Keir Starmer met at the White House to discuss their approach to the Russia-Ukraine war, President Vladimir Putin also warned that if Ukraine fires Western missiles deep into Russia, it would mean that Russia was at war with NATO and would respond accordingly.
