Authorities say a knife-wielding man stabbed several people in Paris on Saturday before he was shot and killed by police. The incident took place near the city's famous opera house.
Local police say at least four people were wounded, two severely and two with minor injuries and at least one victim was killed in the attack. Police have not yet revealed the suspect's identity. His motive is currently unclear.
Paris prosecutor Francois Molins said Saturday, based on testimonies, the attacker shouted "Allahu Akbar," which is Arabic for "Allah is the Greatest." The investigation has been handed to the anti-terrorism section of the prosecution office.
The news agency for the Islamic State of Iraq and Syria (ISIS) later claimed the suspect in the attack was one of its "soldiers."
Witnesses said the attacker ran toward police yelling "kill me or I'll kill you."
Video posted to social media showed police surrounding a man lying on the ground as bystanders in the area frantically fled the scene.
Interior Minister Gerard Collomb denounced the "odious attack" on Twitter and applauded the police for quickly "neutralizing the attacker."
