The 69-year-old had opened fire on several people outside the cultural centre in the French capital, killing three.

Surveillance camera footage shows the suspect in the shooting at a Paris Kurdish cultural centre walking into a barbershop, gun in hand, before being overpowered by men at the back of the premises.

Moments earlier, the 69-year-old had opened fire on several people outside the cultural centre in the French capital, killing three. The pensioner later admitted his intention was "to murder migrants" in a city north of Paris, with a large population of foreign origin.

On Sunday, the prosecutor's office said the man was driven by "pathological hatred."

Members of France's Kurdish community and anti-racism activists joined together in mourning and anger on Saturday in Paris after three people were killed at a Kurdish cultural centre.

The shooting in a bustling neighbourhood of central Paris also wounded three people, and stirred up concerns about hate crimes against minority groups at a time when far-right voices have gained prominence in France and around Europe in recent years.

The suspected attacker was wounded and detained, and transferred on Saturday to psychiatric care, the Paris prosecutor's office said.
