Pentagon spokesman Bryan Whitman says Abd al Hadi al-Iraqi is now being held in the U.S. military's detention center at Guantanamo Bay, Cuba.
Whitman said the suspect has ties to extremists who are allies of Al-Qaeda militants in Pakistan and in Afghanistan.
The Pentagon spokesman says al-Iraqi was caught while trying to reach Iraq.
Security officials in Afghanistan and Pakistan have welcomed news of the arrest, saying it is a successful blow against international terrorism.
Musharraf has survived two assassination attempts in Pakistan that he says were planned by Al-Qaeda operatives.
Meanwhile, U.S. military officials in Baghdad said today that their troops detained 17 suspected Al-Qaeda fighters in Iraq.
The officials also say U.S. war planes destroyed a truck rigged with explosives near the volatile city of Al-Fallujah in western Iraq.
The truck reportedly was discovered on the evening of April 27 after information was received from a suspected militant detained by U.S. troops.
The U.S. fighter jets fired precision guided missiles to destroy the truck.
