The Associated Press reports that the two men will face an additional charge for committing acts supporting terrorism. Meanwhile, the Columbus Dispatch provides more information on their arrest and their defense:

The men were stopped while driving for failure to signal a turn Tuesday after a clerk at a RadioShack called deputies to report the two acting suspiciously while buying three disposable, prepaid TracFones. The men bought six more phones from a Wal-Mart at the same strip mall near I-77.

Inside the car, deputies found nearly $11,000 in cash, a dozen cell phones, instructions on accessing and altering computerized passenger and baggage information from Royal Jordanian Airlines, and some airline-flight manifests.

Assistant Prosecutor Susan Vessels accused the men of "very serious crimes" in detailing the suspicious items found in their car and their admission that they bought 600 cell phones in the last month and were after another 300 on a trip south from Dearborn, Mich.

Attorneys for the two men said authorities are overreacting to a legal purchase of phones by two men who are working for a legitimate businessman. He resells the cheap phones at a profit and has been cleared of any terrorism links by the FBI, the attorneys said.

Agent Dawn Clenney, spokeswoman for the FBI in Detroit, could not confirm what the lawyers said. The Marietta case is a matter for Ohio lawenforcement agencies, she said.

The airline-related documents found in the car owned by Houssaiky's mother belong to her, the men's attorneys said. She works for a company that provides ground support for Royal Jordanian Airlines and others at the Detroit airport, they said.

The attorneys suggested the men were stopped and arrested as targets of racial profiling.

UPDATE: Police are looking into more mass cell phone purchases here and here.
