TAMPA, Fla. (AP) - Closing arguments are set in the trial of a Kosovo-born American citizen in federal court for plotting a terrorist attack in Tampa.

The trial of Sami Osmakac, continues Monday. He's the 27-year-old Pinellas County man arrested during a sting operation in 2012 in which he bought weapons, including a car bomb and an ak-47, from a man he thought was an arms dealer.

Osmakac is charged with possessing an unregistered automatic weapon and attempting to use a weapon of mass destruction. He faces life in prison if convicted.

A psychologist retained by Osmakac's attorneys testified on Thursday he began to suffer symptoms of post-traumatic stress disorder after a turbulent airplane ride in 2009. His attorney also said Osmakac suffers from depression and has below-average intelligence.
