Jordan has rejected an extradition request from France for two suspects accused of carrying out a 1982 deadly attack on a Jewish restaurant in Paris, a judicial source said Wednesday.

The alleged mastermind of the attack, which killed six people and wounded 22 others, Zuhair Mohamad al-Abassi, 62, was arrested in Jordan last year.  

The request was rejected because at the time of his arrest an extradition deal between Jordan and France had not entered into force, the source said.

The deal was signed in 2011 but became effective only in July last year, after Abassi, also known as Amjad Atta, was released on bail.

Jordan has also refused to hand over a second suspect, Nizar Tawfiq Hamada, 54, because the statute of limitations concerning the criminal allegations against him expired, the source said.

The decision was taken in October, four months after French Foreign Minister Laurent Fabius urged Jordan to "respect international procedure" by extraditing Abbasi and Hamada.

David Pere, a lawyer for the AFVT association that represents French victims of terrorism, said he was "astounded" by the Jordanian decision.

"We were expecting the Jordanian authorities to send a strong message in the fight against terrorism," Pere said.

He said Amman's decision not to extradite the pair was a "political" one aimed at "keeping social peace in Jordan."

A French judiciary source said Paris was "not surprised" by the decision.

The attack on the Chez Jo Goldenberg Jewish restaurant - in the popular Marais district of Paris - began around midday on August 9, 1982 when a grenade was tossed into the dining room.  

Two men then entered the restaurant, which had around 50 customers inside, and opened fire with "WZ-63" Polish-made machine guns. They also shot at passers-by as they escaped.

Between three and five men are thought to have taken part in the attack, which was blamed on the Palestinian terrorist group Fatah Revolutionary Council, also known as the Abu Nidal Organization.

Two other suspects have been named as Mahmoud Khader Abed Adra, alias Hicham Harb, who lives in Ramallah in Samaria, and Walid Abdulrahman Abu Zayed, alias Souhail Othman, a resident of Norway.
