French authorities have detained a 72-year-old man considered a key suspect in a grenade and gun attack on a Jewish restaurant in Paris in 1982, in which six people were killed.

Hicham Harb was extradited by the Palestinian National Authority on Thursday, in response to a request last September by France's National Anti-Terrorism Prosecutor's Office (PNAT).

Harb, whose real name is Mahmoud Khader Abed Adra, is suspected of directing the attack in the Rue des Rosiers and acting as one of the gunmen who shot at diners.

French President Emmanuel Macron thanked the Palestinian Authority and said it was "a concrete demonstration" of judicial co-operation resulting from France's recognition of a Palestinian state in September 2025.

On arrival at the Villacoublay air force base near Paris, Harb was placed in detention, PNAT said.
