GUANTANAMO BAY NAVAL BASE, Cuba AP _ A Yemeni admitted he was a driver for Osama bin Laden and knew of the al-Qaida leader’s role in the Sept. 11 attack, an FBI agent testified Thursday, countering defense assertions that the detainee was a minor employee with no role in terrorism.

Salim Ahmed Hamdan told FBI agents that he had chauffeured bin Laden around Afghanistan in an al-Qaida convoy after Sept. 11 and overheard the leader say he had expected only up to 1,500 people to be killed in the attack, Special Agent George Crouch said.
