Osama's son lived in Karachi 'safe house' with wife in 2002

The report, part of the hundreds released by whistle-blower website Wikileaks, say Pakistani authorities in 2002 had discovered over 20 passports, most of which were valid, belonging to the wives and children of bin Laden during a raid conducted at an al-Qaeda safe house.

The information was given by Abdul Rabbani Abu Rahman who is alleged to have closely worked for bin Laden and managed things for the mastermind of the 9/11 attacks.

He is also alleged to have worked directly for Khalid Sheikh Mohammad, one of the main accused in the attack on the twin towers in New York.

As per the details of the report prepared on June 9, 2008, Rahman was arrested in a joint operation by Pakistan's military-run intelligence agency ISI and securitymen on September 10-11, 2002.

He was moved to Guantanamo Bay two years after his arrest after having been questioned in Pakistan and Afghanistan.

"Detainee admitted working directly for Khalid Sheikh Muhammad... as an al-Qaeda facilitator from early 2000 to September 2002.

"Detainee's duties included managing several Karachi, Pakistan (PK), safe houses. Detainee had direct access with many high-level al-Qaeda members, including Osama bin Laden; Ayman al-Zawahiri; Muhammad Atef aka (Abu Hafs al-Masri); and Nashwan Abd al-Razzaq Abd al-Baqi, aka (Abdul Hadi al-Iraqi)..." the report signed by a Rear Admiral said.

The report said Rahman met bin Laden on numerous occasions. He met bin Laden twice at the Kandahar Airport in Afghanistan and twice at the al-Qaeda leader's guesthouse near the Kandahar Airport.

The detainee reported that bin Laden's son, Saed bin Laden, "lived in Karachi with his wife and son, from January 2002 through at least June 2002."

"KU-10024 (a code used for another detainee) provided a safe haven for Saed in Karachi. While Saed was there, he would occasionally come with KU-10024 to one of the detainee's safe houses located at house number D-255, Block 13 D1, Gulshan-I-Iqbal, Karachi," the report said.

It said during a raid on Rahman's safe house located on Tariq Road here, Pakistani authorities discovered over 20 individually wrapped passports, most of which were valid passports belonging to the wives and children of Osama bin Laden, stored next to remotely-activated electronic detonators.
