Around 100 members from the Ligue de Défense Juive (LDJ) protested on Thursday night in front of the Paris offices of the AFP news agency, reported the Metro newspaper.
The mob then tried to storm the offices of the AFP news agency, prompting riot police to spray them with tear gas.
Claiming to be unhappy about the agency's coverage of conflicts in Israel and Palestine, masked protestors launched firecrackers while yelling "Islamic terrorists" at journalists at the scene.
They then attacked Buzzfeed France journalist David Perrotin, who was live-tweeting the protest, and who had written about the group in the past.
The editor of Buzzfeed France tweeted on Friday that Perrotin was safe and was under protection.
The French LDJ denies breaking French laws, yet takes inspiration from the far-right Jewish Defense League, labelled a "violent extremist organization" by the FBI in 2001 and banned in both the US and Israel.
It also uses the emblem of a banned Israeli far-right party, the Kach, a raised fist inside a black Star of David, set against a yellow backing.
