250 kilometers northeast of Benghazi, Libya, several hundred ISIS veterans arrested between 2014 and 2019 are detained in the Guernada military prison. All more dangerous than others, according to the Libyan authorities who have, for the first time, opened the prison doors to a foreign television.

Led by General Jalal Abdel Hakim, this detention center is made up of 60 cells. Its purpose: to prevent the propagation of radical ideas spread by the terrorist group.

Most of the prisoners were arrested by Marshal Khalifa Haftar's forces during his recent conquest of the eastern part of the country in April. For years, many of them have been waiting for a judgment that does not happen.
