[Russian Ministry of Foreign Affairs summoned Senior diplomats of the US Embassy in Russia] on 26 May, the Russian Foreign Ministry urgently summoned senior diplomats of the US Embassy in Russia to strongly protest against the remarks made by Sullivan, assistant to the US president for national security affairs, that Ukraine had launched an attack on Russian territory. The Russian Foreign Ministry stressed that US officials' pledge not to encourage Ukraine to launch attacks on Russian soil is a lie. The United States has long been a party to the conflict, and the hostile actions of the United States have put Russian-US relations in crisis. The United States should understand as soon as possible that any form of aggression against Russia will be the most resolute counterattack by Russia.
