The BBC is reporting this morning that what it calls a rogue Russian pilot" tried to shoot down an RAF aircraft in 2022. It claims sources have shed new light on an incident that had already caused some controversy.

In October 2022 the then UK defence secretary, Ben Wallace, revealed that a Russian fighter jet released a missile" in the vicinity of a British aircraft in international airspace over the Black Sea because of a technical malfunction.

Three senior western defence sources with knowledge of the incident have told the BBC that Russian communications intercepted by the RAF RC-135 Rivet Joint aircraft give a very different account from the official version.

The intercepted communications show that one of the Russian pilots thought he had been given permission to target the British aircraft, following an ambiguous command from a Russian ground station.
