Oussama Abdullah Kassir, 43, is charged with supporting both terrorism and Al Qaeda when he allegedly tried to establish the camp in the northwestern US state of Oregon in 1999.
Jury selection began at a New York federal court Monday and opening statements in the trial could come this week.
Kassir, a Swede of Lebanese origin, was arrested in 2005 by Czech authorities in response to a US request to Interpol while he was at an airport stopover between Stockholm and Beirut.
According to prosecutors, the camp in Bly, Oregon “was to provide a place where Muslims could receive various types of training, including military-style jihad training, in preparation for a community of Muslims to move to Afghanistan.”
However, the training facility was never put into operation.
