WASHINGTON — A key al-Qaida operative returned to Pakistan by the CIA after he gave the U.S. information that eventually led to the location of Osama bin Laden has since rejoined al-Qaida, U.S. officials say.
The agency returned Hassan Ghul to Pakistan not long after the CIA closed its remaining secret prisons in Eastern Europe in 2006.
The CIA had been given assurances that Ghul, a native of Pakistan, would not go free. But Pakistan failed to keep its word. Ghul was let go and later rejoined al-Qaida, angering the CIA officers who worked so hard to take him off the battlefield, according to former and current U.S. intelligence officials.Story: Pakistan arrests C.I.A. informants in bin Laden raid
Pakistan's decision to free Ghul is yet another troubling revelation at a time when the U.S. is rethinking its relationship with Pakistan and whether it can be a trusted ally in fighting terrorism. Members of Congress have talked about ending aid to Pakistan after bin Laden was found inside Pakistan, hiding out in an urban area not far from a military garrison. Last week, CIA Director Leon Panetta confronted Pakistan's intelligence service about tipping off militants running bomb factories aimed at killing U.S. soldiers in Afghanistan.
Ghul's return to Pakistan also raises questions about how the Bush administration, which was committed to keeping arguably less dangerous detainees locked up at the U.S. prison at Guantanamo Bay, Cuba, could hand over the man who provided the key information about bin Laden's trusted courier, intelligence that in May led to bin Laden's death at the hands of U.S. commandos.
The move frustrated former CIA officers, who at the time believed Ghul should have been moved to Guantanamo along with 14 other high-value detainees like Abu Zubaydah, a major al-Qaida facilitator, and Khalid Sheikh Mohammed, the mastermind of the 9/11 attacks.
A U.S. official said Pakistan made promises that it would hold Ghul, only to let him go and re-establish contact with al-Qaida. A senior Pakistani intelligence official said he had no information about Ghul.
The officials spoke on condition of anonymity because details about Ghul's case remain classified.
Former CIA officials say Ghul was part of Zubaydah's clandestine network of moneymen and couriers. He was well-known to the CIA before the 9/11 attacks. The CIA had been pressing Pakistan to arrest Ghul for years and later learned after 9/11 he had been hiding at safe houses in the Lahore area belonging to the terrorist group, Lashkar-e-Taiba, which was behind the 2008 attacks in Mumbai, India.
But Pakistan's spy service, the ISI, refused to pick up Ghul.
When the CIA figured out that Ghul was traveling to meet with al-Qaida operatives who had gone to Iraq after the 2003 invasion to fight the U.S., the agency decided to act. In a joint operation with the Kurds, Ghul was nabbed in northern Iraq in January 2004, former CIA officials said. Pakistan was furious when it learned the CIA had Ghul and pressed the U.S. to return him.
Instead, Ghul was taken to Bagram Air Base in Afghanistan but was later removed over questions about whether the transfer was legal, former CIA officials said. Ghul then was taken to a CIA "black site" — a secret prison — in Eastern Europe and provided crucial information about bin Laden's most trusted courier before he was exposed to harsh interrogation techniques. Ghul's information later allowed the CIA to realize that finding the courier probably would lead to bin Laden.
Ghul also provided key information about the whereabouts of terrorists in Pakistan's lawless tribal areas, the officials said. He provided other precise information as well.
"He was very useful," a former CIA officer said.
Former CIA officials said in the rush to close the secret prisons, the U.S. was looking for ways to get rid of some of the remaining two dozen or so detainees in the agency's now-defunct interrogation and detention program. With Pakistan offering to take Ghul, U.S. officials figured they could also build some good will by giving him back, and the CIA had the ISI's pledge that he wouldn't go free.
It's not clear why Pakistan wanted Ghul back so badly, but former CIA officers who targeted Ghul said he had ties to the Lashkar-e-Taiba terror group, which had the backing of ISI.
Little is known about Ghul's movements after he was sent back to Pakistan. At an undisclosed location in Pakistan, Ghul talked with a British detainee named Rangzieb Ahmed who was held in an adjacent cell. Ghul told Ahmed that he had been held in a secret CIA location for 2 1/2 years and had also passed through Morocco.
Ahmed said the last time he saw Ghul was in January 2007.
