Shamsadi Berbetov, the uncle of Paris knife-attacker Khamzat Asimov, recalled the “shy lad” he knew in an exclusive interview in the Russian city of Argun on Tuesday. “He went away sometime in 2002. We kept in touch. Sometimes he came home. He was a shy lad or still is. We do not know for sure whether he is alive or not. We know what is being said on TV. We do not know anything else,” he said... Еще. Speculating on the reasons behind the attack, Berbetov said “most likely, it was some sort of fight, probably, in a café, in a bar. We do not know. Maybe it was a terrorist attack. We do not have any idea. So, we have nothing to say.” On May 13, the knife-attacker, identified as 21-year-old French national Khamzat Azimov, who was born in Chechnya, assaulted passers-by, killing one person and injuring four more. The attacker was shot dead by police. French authorities have opened a terrorism investigation into the stabbing attack, responsibility for which was claimed by the self-proclaimed Islamic State (IS; formerly ISIL/ISIS).
