Washington denied that Ukraine was involved in the armed attack that left dozens dead in a concert hall in a suburb of Moscow the day before Friday. US National Security Council spokeswoman Adrienne Watson said that ISIS, which claimed responsibility for the attack, alone bears responsibility.

In turn, Ukrainian President Volodymyr Zelensky said that Putin is trying to hold Ukraine responsible for the "terrorist" attack in Moscow. Putin said, "We will identify everyone who stood behind the terrorists and everyone who prepared the attack," and continued, "They will face an unenviable fate"
