On the eve of the first anniversary of the Islamic State (Isis) terrorist attacks on Paris, it has emerged that 20 survivors of the massacre at the Bataclan theatre remain in hospital. A documentary that will air on Sunday (13 November) in France examines how the attacks, which claimed the lives of 130 people, have affected those bereaved or injured.

Ninety people were killed when gunmen stormed the Bataclan on 13 November 2015 during a performance by a US rock band, The Eagles of Death Metal. Among the dead was the wife of Antoine Leiris, a 35-year-old father who became the face of the many victims, living and dead, when he posted a moving letter on social media, just days after the attacks.

In the letter, which went viral, Leiris told his wife's killers: "Of course I am devastated with grief, I will give you that tiny victory, but this will be a short term grief... We are only two my son and I, but we are more powerful than all the world's armies. In any case, I have no more time to waste on you."

A year on, Leiris who fronts the documentary, told AFP: "We are the ones left behind, stalked by the same shadow, united by the idea that we must not be killed a second time.

"I was a sort of totem to which people rallied, a symbol of someone who was trying to pick themselves up. But I'm just a normal person... There are days when I'm afraid, days when I want to flee, days when I want to smash everything to pieces, like everyone else."

The impacts of the attacks on a number of bars and restaurants and near the Stade de France where an international football friendly was taking place between France and Germany, have been wide-ranging.

As well as the 130 victims, 400 were injured and 2,000 are said to be receiving treatment for trauma, Additionally, 1,000 people lost a relative in the attacks, 50 of whom were children who lost a parent.
