The Russian foreign ministry has summoned the American ambassador to protest against what it says was the use of US-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, adding: “Retaliatory measures will certainly follow.”
