In the 2015 Paris attacks, the main suspect told a court that his job title is "a fighter for Islamic State."

Salah Abdeslam is one of 20 persons accused of being part of the terrorist atrocity in which 130 people were killed, and hundreds more were injured.

The attackers, part of the Isis network, attacked restaurants, clubs, the Stade de France stadium, and the Bataclan concert theater with weapons and bombs.

Authorities believe Abdeslam, 31, is the lone surviving member of the cell responsible for the November 2015 attack.

He was questioned about his occupation as he entered a purpose-built courthouse in Paris, where security was on high alert to protect proceedings, dressed in all black.

After a prayer, he told the court he is a "fighter for Islamic State," according to the Associated Press.

He has so far refused to speak to police about the attack, making it difficult to figure out who was responsible. One of the suicide bombers was his brother.

19 other men are accused of being involved, either by providing guns or automobiles or by assisting with the organization.

In 2016, the same cell was suspected of killing 32 people in Brussels.

"The events that we are about to decide are inscribed in their historic intensity as among the international and national events of this century." declared the judge, Jean-Louis Peries.

The trial is slated to last nine months, with the focus on police evidence beginning in September.

Former French President Francois Hollande, who was in charge of the assault, will also testify in the case.
