Xavier Lesaffre, an emergency doctor on the November night in 2015 when terrorists unleashed mayhem on Paris, collects his thoughts carefully before recalling the sequence of events that led him from a dinner party with friends to the epicentre of the carnage at the Bataclan concert venue. A decade on, he says he still asks himself why the attacks happened and what has changed since.
"What worries me is all the dissension that we feel in our society," he told RFI. "I think that's been something the attacks have contributed to ... more violence and more tension in our society."
