Tunisia's ousted president possessed more than $13 billion in assets, a government commission formed to look into his wealth has found, according to a Monday report from the local TAP news agency. Head of the confiscation commitee, Najob Hnane, said they had identified 398 holding companies, as well as several other assets, belonging to ex-president Zine El Abidine Ben Ali and his relatives. Other assests are believed to exist, Hnane added. Some of the confiscated assets will be displayed in a November exhibition in the northern resort town of Gammarth, according to a minister for state property, Selim Ben Hmidane. "The revelations about these assets show the involvment of a Mafia with branches abroad," said Ben Hmidane. Among the items confiscated from the Ben Ali family and their associates were drugs, explosives and foreign passports. Ben Ali fled to Saudi Arabia in mid-January 2011 following a month of popular protests against his autocratic rule. In July, a Tunisian military court handed him a life sentence in absentia for his role in killing protesters during the uprising.
