Russia summons the American ambassador over a deadly attack that Moscow says used US-made missiles

The Russian Foreign Ministry summoned the American ambassador on Monday to protest what it says was the use of U.S.-made advanced missiles in a Ukrainian attack on Russian-annexed Crimea that reportedly killed four people and wounded more than 150. Washington “has effectively become a party” to the war on Ukraine’s side, the ministry said in a statement, adding, “Retaliatory measures will certainly follow.” The Associated Press could not independently verify Russia's claims about the missiles used.
