Hamza is no stranger to prison, as he was sentenced in absentia to 12 years behind bars in his native country of Tunisia, and served a seven-year sentence in 2000 after being apprehended for the murder of a fellow al-Mujahideen combatant.
Hamzi to nije prvo zatvorsko iskustvo: bio je osuđen u odsustvu na 12 godina u svom rodnom Tunisu, a odslužio je sedmogodišnju kaznu 2000. godine pošto je uhapšen zbog ubistva saborca iz jedinice al-Mudžahedin.
