The Russian Security Council believes that Ukraine is behind the terrorist attack in Moscow. The attack was committed by the Islamic State, which is recognized as a terrorist organization by the Supreme Court of the Russian Federation.

The U.S. government is trying to cover up the attack with the mention of the Islamic state, according to the Russian Foreign Ministry representative in the United States. The United States is also trying to hide the fact that the attack was carried out by Islamic State terrorists, the Russian official said.
