Oussama Kassir was arrested last month at the airport in the capital, Prague. He has been charged in the United States with planning to set up a terrorist training camp in the western state of Oregon.
Czech authorities are awaiting an official extradition request from the United States.
Kassir, a Swede of Lebanese origin, told Czech television he had visited the U.S. on vacation in 1999, but he was not there to set up a terrorist camp.
