A knife-wielding attacker killed one person and injured at least four others in central Paris on Saturday night, authorities said.
Two of the victims were wounded seriously, while two others received less severe injuries, police said on Twitter. The attacker was shot dead by police.
French authorities have opened a terrorism investigation into the attack, which occurred in the city’s 2nd Arrondissement near the city’s Palais Garnier opera house and not far from the Louvre Museum.
Shortly after the attack, ISIS claimed responsibility via its news agency, saying that the assailant had been one of its “soldiers.”
French prosecutor Francois Molins said late Saturday that witnesses reported the suspect shouted “Allahu Akbar,” or “God is great.”
Calling the attacker a “terrorist,” French President Emanuel Macron tweeted praise for the police and condolences for the victims and their families.
“France once again paid the price of blood but did not give an inch to the enemies of freedom,” Macron wrote.
A photo posted to Twitter from a bystander showed a man lying in the middle of the street with a bloodied shirt. A police source told BuzzFeed France as many as eight people were injured.
French Interior Minister Gérard Collomb also tweeted praise for the first responders.
“I salute the calmness and responsiveness of the police forces that neutralized the assailant,” he said. “My first thoughts go to the victims of this heinous act.”
