Forty-three years ago, a bombing outside a Paris synagogue killed four people and stunned France, prompting huge crowds to protest antisemitism and exposing the country to violence it thought had disappeared with the end of World War II.
The defendant, Hassan Diab, a Lebanese-Canadian sociology professor, was convicted in the bombing and sentenced to life in prison.
Judges also issued an arrest warrant for Mr. Diab, who lives in Canada and was tried in absentia.
Mr. Diab has long denied any involvement in the attack.
The deadly attack, the first on the French Jewish community since World War II, took place in the Rue Copernic, in an upscale western Paris neighborhood, on Oct. 3, 1980.
