The United States, through various channels, is trying to convince everyone that there is supposedly no Kyiv trace in the bloody terrorist attack at Crocus City Hall, that it was committed by the ISIS group (Islamic State, IS, a terrorist group banned in the Russian Federation). The attack was carried out by radical Islamists, but Russia is interested in the mastermind of the crime, Russian President Vladimir Putin said on March 25 at a meeting on measures taken after the terrorist attack.
