Ministry of Defense Confirms: Russia has shot down a British Storm Shadow Cruise Missile
The trouble with this is simple, that missile can only be fired by NATO aircraft. Which means a NATO plane launched it either in or near, Ukraine.

Ukraine does NOT have any of those aircraft. So who fired it?
Since Ukraine doesn't have any NATO type of fighter jets. They are probably launched from Polish or Romanian airspace from NATO jets.
