At around 9 p.m. an assailant armed with a knife and shouting “Allah Akbar” stabbed passersby about half a mile from the Palais Garnier (Opera House) located in the 9th arrondissement in central Paris. The attacker killed one person and wounded four, two of them seriously, before he was shot dead by police. Shortly after the attack, the Islamic State (IS) claimed responsibility via its Amaq news agency, but provided no proof for its claim. Authorities later identified the attacker as a 21-year old Chechnya born Frenchman, who had been on a terrorist watch list as a potential security risk. France has been on high alert amid a series of attacks, commissioned or inspired by the IS, that has killed over 240 people since 2015.
