A man wanted over a deadly attack on a Jewish restaurant in Paris more than 40 years ago has been arrested by Palestinian authorities in the occupied West Bank.

Mahmoud Khader Abed Adra - who went by the name Hicham Harb - is suspected of directing the August 1982 gun and grenade assault on the Jo Goldenberg restaurant on Paris's Rue des Rosiers, which killed six people and left at least 20 injured.

News of the arrest comes just days before France plans to formally recognise the state of Palestine.

President Emmanuel Macron said he welcomed the "excellent co-operation" between France and the Palestinian Authority in a post on X.

"We are working together to ensure his swift extradition," he added.
