Paris attacks suspect Salah Abdeslam has been extradited from Belgium and placed under formal investigation on terrorism and murder charges in France.
Belgium-born Abdeslam is believed to be the sole survivor of a group of Islamist militants who killed 130 people in Paris on November 13.
Abdeslam, 26, was Europe's most wanted fugitive until his capture in Brussels on March 18 after a four-month manhunt.
Four days after his capture, other Islamist militants blew themselves up at Brussels international airport and on a metro train, killing 32 people.
Investigators have said Abdeslam told them he arranged logistics for the multiple suicide bombings and shooting attacks in Paris, and had planned to blow himself up at the Stade de France sports stadium before backing out at the last minute.
His French lawyer says Abdeslam promised to talk to judges at his next hearing.
"The investigation will determine to what degree he was involved in the acts," lawyer Frank Berton said. "He stayed silent today but said he would talk at a later stage."
Abdeslam did not speak on Wednesday (local time) because he was tired after a "quite rough" extradition, Berton said.
Sven Mary, Abdeslam's main defence lawyer in Belgium, distanced himself from his client, telling France's Liberation newspaper: "He's a little jerk from Molenbeek, from a world of petty criminals -- more of a follower than a leader, with the brains of an empty ash-tray."
