Dr Philippe Jouvain is head of Accident and Emergency at the Georges Pompidou Hospital, just outside of Paris. He was at a restaurant in the city on Friday when he got what's known as a "white call". Dr Jouvain has worked as a doctor in Afghanistan - but he told Rebecca Kesby that he'd never seen anything like the scenes on Friday night.
