KABUL, Afghanistan (AP) — Afghan President Hamid Karzai is denouncing the seizure of a university student by armed Afghans that his spokesman says work for the CIA.

Karzai spokesman Aimal Faizi told The Associated Press on Sunday that the CIA freed the student after Karzai’s staff intervened. But Faizi says Karzai wants the armed Afghans arrested and will ban foreign forces from universities.

Faizi says the raiders fired shots as they grabbed the student Saturday from a Kandahar university. He says they interrogated him at a CIA post that Taliban leader Mullah Omar once used as a home.

The CIA could not be reached for comment.

The agency has trained an Afghan counterterrorist force that U.S. officials say works with Afghan intelligence. They spoke anonymously because they were not authorized to speak publicly.
