At least three people were killed, and several others wounded. Prosecutors said they were looking into a possible racist motive for the attack, as an investigation into the incident was opened. Multiple gunshots were fired on a street lined with small shops and cafes in the capital's busy 10th district.
Authorities said a 69-year-old man was arrested. The prosecutor said the suspect had been detained a year ago for an attack with a saber on a migrant camp in Paris. Reuters was not immediately able to contact the suspect's representatives.
Local media reported the suspect to be a French national.
