Attack on Nice: 'Terrible scenes and terrible images in their heads'

Psychiatrist Dr Sylvie Serret treated many people - including children - who witnessed the traumatic attack in Nice.

Eighty-four people died in Nice when Mohamed Lahouaiej-Bouhlel drove a lorry into crowds marking Bastille Day on the Promenade des Anglais on Thursday before he was shot dead by police.

Dr Serret describes what she had to deal with when they arrived at hospital.
