ISLAMABAD: A former Pakistani intelligence officer disclosed the hideout of Osama bin Laden to CIA in exchange for $25 million bounty on the head of the al-Qaida chief, who was living as prisoner under ISI protection in the garrison town of Abbottabad, according to a report.

"In August 2010 a former senior Pakistani intelligence officer approached Jonathan Bank, then the CIA's station chief at the US embassy in Islamabad. He offered to tell the CIA where to find bin Laden in return for the reward that Washington had offered in 2001," Dawn reported, citing American investigative journalist and author Seymour M Hersh.

The intelligence official, Hersh said, was a military man who is now living in Washington and working for the CIA as a consultant. "I cannot tell you more about him," he said.

The US confirmed the information provided by the official and put the compound under satellite surveillance. Americans later informed the ISI which set up a cell in Ghazi, Tarbela, where "one man from the SEALs and two communicators" practised the raid before executing the operation, Hersh said, adding that it was difficult decision but Pakistan was ultimately taken on board and told about the script to kill Osama.

Hersh said that whatever the Obama administration told about the operation to kill Osama was part of fiction and the real story was totally different.

"The most blatant lie was that Pakistan's two most senior military leaders — Gen Ashfaq Parvez Kayani (the-then army chief) and Gen Ahmed Shuja Pasha (the-then ISI chief) — were never informed of the US mission," he told Dawn.

When the Americans contacted the Pakistani government and asked for Osama, the ISI insisted that he be killed and his death should be announced a week after the operation.

Hersh said the Saudi government also knew about Osama's presence it Abbottabad and had advised the Pakistanis to keep him as a prisoner. "Osama was an ISI prisoner and never moved except under their supervision," he said.

The Americans were required to say that the al-Qaida chief was found in a mountainous region in the Hindu Kush so that neither Pakistan nor Afghanistan could be blamed for keeping him, Hersh said, adding that the ISI wanted him dead because "they did not want a witness".

Hersh said President Barack Obama did not consult Gen Kayani and Gen Pasha before releasing the cover story that he shared with his nation in a live broadcast.

"The cover story trashed Pakistan. It was very embarrassing for them," said Hersh. "Pakistan has a good army, not a bad army, but the cover story made it look bad."

Hersh also said that Dr Shakil Afridi, the physician now jailed in Peshawar for helping CIA trace down Osama's hideout, was a CIA asset but he did not know about the operation. Afridi was used as a cover to hide the real story, he said.

Osama was killed in Abbottabad on the night of May 2, 2011, in a covert raid conducted by US navy Seal.
