France detains Nice footballer Atal over post on Israel-Hamas war
Last month the 27-year-old defender was banned for seven matches over the post, which he quickly deleted and subsequently issued an apology.
The public prosecutor in Nice opened a probe following a request from the local prefect and mayor of Nice.
Prosecutors later said that Atal will face trial for incitement to religious hatred on December 18 at the Nice criminal court.
He had already been suspended by his club "until further notice".
Despite the player's apology, OGC Nice said that it decided to "take immediate" action, "prior" to any sanctions that might be taken by sporting or judicial bodies, "given the nature of the publication shared and its seriousness".
In mid-October, the Nice public prosecutor announced the opening of an investigation into "justification of terrorism."
Atal has been criticised for sharing a video from a Palestinian preacher on Instagram, purportedly calling for violence against Jewish people.
AFP was unable to independently verify its content.
France, which has large Jewish and Muslim populations, ramped up security after Hamas launched massive attacks on Israel on October 7.
Israeli officials say the attacks killed 1,200 people, mostly civilians, and about 240 people were taken hostage.
Israel has vowed to destroy Hamas and its retaliatory air and ground offensive in the Gaza Strip has killed nearly 15,000 people, thousands of them children, according to the Hamas government of the Palestinian territory.
