In France, a historic trial has begun over the 2015 Paris attacks, which killed 130 people.
The shooting and bombing attack by extremists from the Islamic State (IS) group was France's worst post-World War Two tragedy.
Salah Abdeslam, the only surviving attacker, is in court with 13 other defendants in a specially created facility in Paris.
The trial is being dubbed "the biggest in modern French history."
There will be approximately 140 days of hearings over the following nine months, involving about 330 lawyers and 1,800 survivors and relatives of victims. Around 300 witnesses, including François Hollande, the French president at the time of the attacks, will be heard.
Mr Hollande told French media before of the trial that it was a crucial time for the victims of the assaults, which he called as an "act of war" at the time.
On November 13, 2015, IS acknowledged to carrying out attacks on the Bataclan concert venue, a large stadium, restaurants, and bars.
On Wednesday morning, the suspects came in police vans surrounded by strong security. Before the trial began, they were ordered to sit together in the defendants' box, wearing face masks.
The defendants were brought in a little while ago, half an hour late. Abdeslam was the last to arrive, clothed in a black T-shirt and sporting a thick beard.
When the presiding judge asked him what he did for a living, he replied that he was an IS soldier.
Security police have cordoned off half of the Île de la Cité, central Paris' biggest island, for the trial. There is a crowd of police, attorneys, media, survivors, victims' relatives, and psychiatric support workers inside the courtroom.
There was that deceptive sense of calm that often precedes large trials like this, with participants conversing seemingly merrily together - in truth, they were on pins and needles waiting for the start of what promises to be a historic event.
Philippe Duperron, whose son Thomas was killed in the Bataclan assault, had mixed emotions regarding the trial, including impatience and fear.
"It will be the occasion for all the victims to bear witness, so it will be a very painful moment and bring back the pain again," he said.
