The Foreign Office summoned Moscow’s ambassador to London this afternoon to complain about a flight by two Russian bombers over the Channel, which the UK says posed as a potential danger to civilian flights.

The Ministry of Defence confirmed that RAF Typhoon jets were sent to intercept a pair of Tupolev 95 “Bear” planes on Wednesday, as they flew along the south coast of the English Channel. A spokeswoman from the Ministry Defense said in a statement released after the incident that, “The Russian planes were escorted by the RAF until they were out of the UK area of interest. At no time did the Russian military aircraft cross into UK sovereign airspace.”

The UK is waiting for an explanation from Russia.
