PARIS -- The person who stabbed five people Saturday night yelled the Arabic phrase "Allahu Akbar," meaning "God is great," during the attack, Paris prosecutor François Molins told reporters at the scene.
One person was killed and four others were wounded during the Saturday night knife attack before the assailant was killed.
The media wing of ISIS claimed responsibility for the attack in a statement published online.
The Amaq News Agency said "the person who executed the stabbing in Paris is a soldier of the Islamic State." The statement also said he acted in response to calls to attack anti-ISIS coalition countries.
ISIS did not provide proof to substantiate the claim and no authorities or security sources have yet verified the authenticity of the ISIS claim.
Two of the victims were gravely injured and two others were lightly injured, according to police. The attacker is also dead, police tweeted.
French Interior Minister Gerard Collomb praised the cool and quick response by French police who "neutralized" the assailant.
"My first thoughts are for the victims in this odious attack," added Collomb, who made the comments via Twitter.
Paris Mayor Anne Hidalgo saluted the courage and professionalism of police, writing on Twitter that they have "again saved lives" and "have all my gratitude."
She also thanked the emergency services who arrived to the attack scene quickly and took charge of the wounded.
The location of the attack is about 10 minutes away by foot from the Paris opera house, known as Palais Garnier, in the city's touristy 2nd arrondissement, or district.
