MOSCOW (Sputnik) — The prime minister added that the investigation was yet to prove the fact, but French officials were certain of the terrorist's sudden turn into Islamism as he never had any "jihadist past."
"Saturday morning's claim by Islamic State [Daesh] and the fast radicalization of the killer confirm the nature of this attack," Valls told the French Le Journal du Dimanche weekly newspaper in an interview.
"I have always told the truth about terrorism: a war is underway, there will be more attacks. It's hard to say, but other lives will be lost," he stressed.
On Saturday, media reported that IS, which is outlawed in many countries, including Russia, claimed responsibility for the attack.
