PARIS, Nov 27 (Reuters) - Six teenagers go on trial behind closed doors on Monday, accused of involvement in the beheading of French history teacher Samuel Paty by a suspected Islamist in 2020 in an attack that struck at the heart of the country’s secular values.

The teacher had shown his pupils cartoons of the Prophet Mohammad in a class on freedom of expression, angering a number of Muslim parents. Muslims believe that any depiction of the Prophet is blasphemous.
