Fezzani was initially acquitted at a first-instance trial and deported in 2012.
Born in Tunis in 1969, Fezzani has been a known militant in Ansar al-Sharia Tunisia, a satellite of Islamist terrorist group al-Qaeda, for the past 20 years. He was first captured in 2002, detained at Bagram Airfield, the largest U.S. base in Afghanistan, then extradited to Italy.
