The teacher had shown his pupils caricatures of the Prophet Mohammad in a class on freedom of expression, angering some Muslim parents. Most Muslims avoid depictions of prophets, considering them to be blasphemous.

Among those on trial was a teenage girl who had allegedly told her parents that Paty had asked Muslim pupils to leave the room before showing the caricatures.

The court found her guilty of having made false accusation charges and slanderous comments, as it was established that she was not in the class at the time.

The other adolescents were found guilty of charges related to taking part in a pre-meditated criminal conspiracy and helping to prepare an ambush.

Paty, 47, was killed outside his school in a Paris suburb by an 18-year-old assailant of Chechen origin, who was shot dead by police soon after the attack.

The court found those adolescents as guilty of having pointed out Paty to the murderer.

The heaviest sentence was given to an adolescent who was told to serve 6 months in prison.
