In a custom-built courtroom, the trial begins for the November 2015 Paris attacks

PARIS — France's biggest criminal trial in contemporary history, for the November 2015 attacks that left 130 people dead, began Wednesday in a courtroom specially built to accommodate the scores of survivors and victims' family members seeking accountability.

On the night of Nov. 13, 2015, attackers deployed a mix of explosives and assault rifles as they targeted the Bataclan concert venue, the national stadium where then-President François Hollande was attending a soccer match, and several cafes and restaurants. The Islamic State later claimed responsibility.
