ISLAMABAD: Osama bin Laden fathered four children as he hid out in Pakistan after the 9/11 attacks, his youngest wife told interrogators, according to a police report seen by AFP on Friday.

Amal Abdulfattah's account provides rare details of the Al-Qaeda leader's life from when he fled Afghanistan in late 2001 until his death aged 54 last May during a U.S. Navy SEAL operation in Abbottabad, in Pakistan.

Abdulfattah, from Yemen, was arrested by Pakistani authorities following the US raid on bin Laden's compound near the Pakistani capital Islamabad, along with two of his Saudi wives, and her five children.

The three widows face charges of illegally entering and residing in Pakistan.

The police report, dated January 19, said Abdulfattah was born into a family of 17 children and married bin Laden because "she had a desire to marry a Mujahedeen".

The report, from the office of the inspector general of police in Islamabad, recommended Abdulfattah and her children be immediately deported.
