Christian Ganczarski, a German citizen who was born in Poland, converted to Islam in the mid-1990s. Ganczarski allegedly traveled from Germany to Pakistan and Afghanistan on five occasions from 1999 through 2001 to support Al Qaeda. During that time, Ganczarski developed a relationship with Osama bin Laden and Khalid Sheikh Mohammed. Ganczarski allegedly transported a potential operative to two Al Qaeda leaders and provided computer and communications equipment to the terrorist group. U.S. authorities are attempting to extradite Ganczarski from France, where he is nearing the end of his prison sentence for his role in the 2009 attack of a synagogue on the Tunisian island of Djerba.
