Seven people have gone on trial in Paris accused of travelling to Syria to train as militant fighters, among them the brother of one of the militants who killed 130 people in the French capital last November.
The seven, aged from 24 to 27, face up to 10 years in jail if found guilty of taking part in an Islamist recruitment network and receiving training in Syria from the Islamic State militant group.
The accused, a gang of friends from eastern France, were part of a larger number who in December 2013 travelled to Syria, where two of them died.
All but one of them returned to France in early 2014. The one who stayed behind was Foued Mohamed-Aggad, who took part in the three-man team that killed 90 people at the Bataclan concert hall during the multiple attacks in Paris.
Two of the three killed themselves by exploding their suicide vests and another was shot dead by police.

Foued's brother, Karim Mohamed-Aggad, is among the seven accused.
The defendants initially told investigators they had believed they were going to Syria on a humanitarian mission.
Several admitted to handling weapons but said they did so under duress.
The group's defence team says the seven were duped and when they realised they had fallen into the hands of a militant network they looked for a way out.
"They were told they could be useful," said Martin Pradel, defence lawyer to one of the defendants, ahead of the hearing. "Their mistake was to believe the propaganda."
His colleague Xavier Nogueras said: "This is the trial of seven youths who came back after three months. That will allow us to highlight the difference between those who decided to come back and the one who stayed."
