Months after hate speech was taken down from Twitter, a French court has ordered the company to hand over details of users who posted anti-Semitic content.
The court, in Paris, issued the order on Thursday in response to a request from the French Jewish students' union (UEJF) and others.
According to Le Monde, Twitter has 15 days following service of the order to unmask users.
If it fails to do so, it will be subject to fines of €1,000 (£850/$1,346) per day.
Twitter has refrained from commenting beyond telling news outlets that it's studying the decision.
Le Monde in October published this collection of anti-semitic jokes on Twitter, after the tag #UnBonJuif (a good Jew) started to make waves.
Other Twitter tags associated with hate speech that have been making the rounds in France include #SiMonFilsEstGay (if my son is gay) and #SiMaFilleRamèneUnNoir (if my daughter brings home a black guy).
Twitter deactivated the accounts in question in October.
