From his Paris window, he saw the Horror of the November 13, 2015 attacks and filmed the terror. Daniel Psenny, who was working as a journalist for French daily Le Monde, witnessed the attack on the Bataclan concert hall, in which 90 people were slaughtered by terrorists. With his mobile phone, Psenny, who lives just a few metres from the venue, filmed the only existing video of the Bataclan attack. FRANCE 24 brings you it as part of this special full-length animated documentary, ahead of next week's trial into the atrocities.
