A man suspected of being involved in a 1982 attack on a Paris restaurant that left six dead and 22 injured was arrested in Norway on Wednesday, the Norwegian security service PST said.
The Norwegian national was arrested in Skien, south-west of Oslo, PST spokeswoman Annett Aamodt said. Aamodt said the arrest was made on "a European arrest warrant issued by France."
In 1982, four assailants threw a hand grenade and then opened fire with automatic rifles on employees and guests at the Jewish restaurant Chez Jo Goldenberg in Paris's Marais district.
The attack has been blamed on the Abu Nidal organization, a now-dissolved militant Palestinian group.
The man, who is in his 60s, earlier told Oslo daily VG that he had never been to Paris.
Aamodt had no comment on the man's stance regarding the allegations. She said he had lived in Norway for a long time.
Charged with murder
France has charged the man with premeditated murder and attempted premeditated murder, according to a Paris court decision, linking him to terrorism, she said. France requested his extradition in 2015.
A remand custody hearing was scheduled for Thursday in Oslo and would include a review of a possible extradition.
Last year, Norway signed onto the European Arrest Warrant system aimed at easing extradition requests.
