The move came after the November 13 series of terror attacks across Paris, when several suicide bombers launched assaults on several venues. The attacks left 130 people killed and over 360 injured. Daesh, also known as ISIL/the Islamic State terrorist group, outlawed in Russia, claimed responsibility for the attacks.
