The man who refuses to give in to hatred

It is nearly a year since the Paris attacks when gunmen burst into the Bataclan concert hall and unleashed hours of violence, targeting those inside with their bullets and their bombs.

Among the 89 people who died that night was 35-year-old Helene Muyal-Leiris. Antoine Leiris is her husband, he says not giving in to hatred is the only way he continues to live.
