Youssef T., 33, has been appearing since Monday before the Special Assize Court in Paris for the car-ramming attack of April 27, 2020. He only went to the mosque during Ramadan.

Except for the Islamic State and Al-Qaeda, he is not aware of any other Islamist terrorist groups. “I sincerely regret what I did. I hurt the victims, society, my family. I tarnished his name,” he says of his alleged attacker, who was killed in the attack.
