The trial of suspects linked to the 2015 terrorist attack on a Tunisian beach resort reopened on Tuesday.
The ISIS attack on the Imperial Hotel in the beach resort of Sousse left 38 people dead, mostly British tourists.
More than 40 people have been summoned to stand trial.
The attacker, a Tunisian student, was killed by police.
Among the accused, 14 have been summoned even though they are not currently being held in custody and it is unclear whether they will turn up for the trial. Six others are security agents accused of failing to prevent or stop the attack.
The trial has been postponed several times at the lawyers' request.
In addition to the massacre at the beach resort, Tunisia suffered two other major attacks in 2015. At the famed Bardo Museum, 22 people died while 12 perished in the center of Tunis on a bus carrying presidential guards.
The attacks devastated the country's tourism sector as travel agencies pulled out and governments issued travel warnings.
Tourism has since bounced back after Tunisia's government implemented a series of measures aimed at securing popular destinations in the country.
