The diplomat took off on an Aeroflot flight to London, from where he will transit to the United States.
Sullivan did not speak to the press before the flight.
On April 15, the United States imposed new sanctions on Russia, including, among other things, the expulsion of ten Russian diplomats from Washington. Moscow responded in the mirror and recommended that the American ambassador temporarily return to his homeland for consultations. The State Department confirmed that Sullivan would leave Moscow but promised that the ambassador would return to Russia in the coming weeks.
The Russian ambassador to Washington, Anatoly Antonov, was summoned to Moscow in mid-March. This happened after the release of an interview with US President Joe Biden. He answered in the affirmative to the question of whether he considers Vladimir Putin a murderer. Antonov remains in Moscow.
