An explosion outside the Stade De France could be heard in the coverage of the France vs Germany football match.
It later became clear that it was the first suicide bomb detonated in the Paris terror attacks in November 2015.
130 people were killed in the attacks outside the stadium, at bars and restaurants and in the Bataclan theatre.
Now, almost 6 years later, it is the largest criminal trial in France's history - and it got underway this morning.
Survivors - such as Olivier Laplaud - will have to relive that night.
"I saw bodies and people shot."
"...and I could hear people moaning in the pit."
"Still today I see them, and I hear them."
Seven On Trial
7 people will go on trial - one accused of being involved in carrying out the attacks.
They will tried in a purpose-built courtroom, with 1,800 plaintiffs and 300 lawyers involved.
It's expected to last until May 2022.
