Tunisian special forces attend an official ceremony inside the barracks of the presidential security service in Gammarth, a suburb of Tunis, on November 24, 2016, paying tribute to 12 presidential security guards killed in a suicide blast a year ago.
The Islamic State group claimed the attack as well as bombings earlier the same year at the Bardo National Museum in Tunis and a beach resort in Sousse that killed 59 foreign tourists and a Tunisian guard. / AFP PHOTO / FETHI BELAID
