Russian President Vladimir Putin dismissed US warnings of a possible terrorist incident in Moscow days before Friday night’s attack. ISIS claimed responsibility for the attack, the scenario was also shared by Washington, but Russia has not yet commented on this topic, Reuters and CNN write.

The United States emphasized on Friday evening, immediately after the terrorist attack in Moscow, that it had warned about the possibility of such an attack.

The US Embassy in Russia even issued a security alert earlier this month, warning of a possible terrorist attack in Moscow and urging people to avoid crowds, monitor local media and be aware of their surroundings.

However, Vladimir Putin reacted harshly to these warnings. As TASS reports, on Tuesday, March 19, three days before the terrorist attack, the Russian president said that the purpose of “the latest provocative statements by some Western official structures regarding the possibility of terrorist attacks in Russia” is to harm Russian society.

“All this looks like pure blackmail and an intention to intimidate and destabilize our society,” Putin said, according to state media.

Shortly after the attack on Friday, ISIS claimed responsibility, according to a Telegram post by a news agency affiliated with the terrorist group.

U.S. officials later confirmed that the attack was claimed by a branch of ISIS, the Islamic State-Khorasan, or ISIS-K. Experts cited by Reuters say ISIS-K has problems with Vladimir Putin and Russia, while officials warn the group could soon attack Western targets.

A White House official shared more information Friday evening.

Earlier this month, the US government had information about a planned terrorist attack in Moscow, prompting the State Department to issue a public warning to Americans in Russia, said Adrienne Watson, spokeswoman for the House National Security Council.

“The U.S. government also shared this information with the Russian authorities in accordance with its long-standing policy obligation of deterrence,” Watson said.

In the end, at least 93 people died as a result of the assault by several armed men in Moscow’s Crocus concert hall.

Russia has not yet commented on ISIS’s statement.
