A Jordanian man who intended to blow up a Dallas skyscraper will be sentenced Monday.

Twenty-year-old Hosam Smadi pled guilty in May to attempted use of a weapon of mass destruction.

In a sting operation, the Federal Bureau of Investigations provided Smadi with what he thought was a truck bomb and timer. In September 2009, he parked it under the 60-story Fountain Place building, set the timer, and left.

The FBI had monitored Smadi since January 2009, posing as members of an al Qaeda sleeper cell.

"Smadi was asked what he would do if he had never met the al-Qaeda 'sleeper' cell," said Tom Petrowski, a supervisory special agent with the FBI in Dallas, in an affidavit. "Smadi replied that he would keep looking for such an entity to be a part of, even if it meant him having to leave the United States and go to Palestine and join Hamas or go back to Pakistan and join the Taliban."

Smadi faces up to 30 years in prison and then deportation under a plea bargain.
