Youngest of bin Laden's three wives was wounded in the US raid that killed the al Qaeda leader last week
One of Osama bin Laden's wives told Pakistani interrogators that the al Qaeda leader and his family had been living for five years in the compound where he was killed by US forces this week, a security official said on Friday.
The official, who identified the woman as Amal Ahmed Abdulfattah, the youngest of bin Laden's three wives, said she was wounded in the US raid on Monday.
The security official said Abdulfattah told investigators: "We have been living there for the past five years."
Both Pakistan's army and its powerful spy agency, Inter-Services Intelligence (ISI), have been facing mounting pressure to explain how it was possible for bin Laden to live deep inside Pakistan undetected for years.
Pakistani security forces took between 15 and 16 people into custody from the compound after US forces removed bin Laden's body, said the security official. Those detained included bin Laden's three wives and several children.
Separately, a senior Pakistani intelligence official briefing Pakistani journalists on Thursday evening said that bin Laden and his deputy, Ayman al Zawahiri, fell out six years ago over the distribution of money. He gave no other details.
US special forces used helicopters to attack the compound in Abbottabad, 50 km (30 miles) north of the capital, Islamabad.
Pakistani security officials say neither bin Laden nor his comrades offered any resistance during the raid.
"From the clues, evidence what we have got is they stormed in with firing shots and knocked them down," a security official said.
Another security official on Thursday said their killing was "cold-blooded."
The raid on the compound, around 4 kilometres (2.5 miles) from Pakistan's main military academy, has further strained relations between the two uneasy allies.
Pakistan's military top brass have expressed anger that the United States did not inform them of the attack beforehand.
In his first comment on the raid, Pakistan army chief General Ashfaq Kayani on Thursday threatened a review of military and intelligence cooperation should the United States repeat similar unilateral action.
He also told senior military commanders that it had been decided to reduce the strength of US military personnel in Pakistan to the "minimum essential."
The army has admitted intelligence failures over the presence of bin Laden in the country and ordered an inquiry into these "shortcomings."
"We didn't know Osama bin Laden was hiding in this house until we took these people into custody and they confirmed that he [bin Laden] has been killed," another security official said.
The military, which has long been seen as the most effective institution of the unstable nation, has also been facing growing criticism at home over the perceived violation of country's sovereignty by the US forces.
It is very difficult to believe anything that is said by Al qaeda or his family. It is much more dificult for the US to fabricate stories since the US is full of whistle blowers not to mention Wikileaks.
But try this: Bin Ladin is old, maybe sick, maybe dying. He allows himself to be shot so he will be a matyr and Al Qaeda will worship him and keep going with their murders.
