The deadly attack on the Bataclan concert hall in Paris a decade ago, along with the shooting at the satirical magazine Charlie Hebdo, marked a turning point in Western Europe: the so-called Islamic State group shattered Europeans' sense of security.
This Thursday marks the 10th anniversary of the assault on the Bataclan, as well as attacks on Paris cafés and the national stadium, which killed more than 130 people and injured over 400.
