ISLAMABAD, Pakistan (CNN) - The identity and nationality of an alleged al Qaeda operative arrested in Pakistan remained shrouded in mystery and conflicting information Monday, a day after Pakistani officials said one of the FBI's most wanted terrorists was in custody.
A Pakistani military official told CNN Monday that the man arrested is a foreign operative linked to al Qaeda. The official did not specifically describe the man as American, and gave no further details.
On Sunday, a senior Pakistani government official told CNN that Adam Gadahn, a U.S.-born spokesman for al Qaeda, had been arrested. A second senior Pakistani government official later confirmed Gadahn's arrest.
But a U.S. intelligence official said there appeared to be no validity to the reports that Gadahn was in custody. Other U.S. officials also said they had no indication Gadahn had been captured.
