The Pakistani people say they do not believe US reports that Osama bin Laden had lived in a compound near a Pakistani military base in Abbottabad since 2005.
The million-dollar compound is located in the city of Abbottabad about 100 kilometers (62 miles) north of the capital Islamabad.
The huge mansion has now been taken over by Pakistan's security forces and the media is not allowed to go inside.
The alleged presence of bin Laden just few hundred meters away from the training center of the military elite has also raised questions about the role of Pakistan's intelligence apparatus, a Press TV correspondent in Abbottabad reported.
The US authorities say Pakistan was unaware of the operation that killed the al-Qaeda leader in his compound in northeastern Pakistan.
Amid a growing controversy about how much Pakistani authorities knew about bin Laden, there are questions that how two US military helicopters landed near Islamabad without the knowledge of Pakistan's Inter- Services Intelligence (ISI) and the military.
US lawmakers and senior officials have urged Pakistan to prove it did not know about bin Laden's hideout.
Reports say it is really hard for the Pakistani people to believe that the entire operation was a surprise for the Pakistani authorities.
Some analysts say there is a possibility that the al-Qaeda militants were living in the compound under the surveillance of ISI when the US military carried out the operation.
They say the operation was a show prearranged between the US and ISI and that bin Laden was not in the house as he had already been killed.
Benazir Bhutto, in a 2007 interview following a failed assassination attempt on her, said bin Laden had been “murdered” years ago.
In response to a question whether any of the assassins had links with the government, Bhutto said, "Yes but one of them is a very key figure in security, he is a former military officer … and had dealings with Omar Sheikh, the man who murdered Osama bin Laden."
US President Barack Obama announced late on Sunday that the al-Qaeda leader had been killed in a military attack on a compound in Abbottabad.
Meanwhile, contradictory stories are emerging from the White House about the military operation. One of the contradictions includes comments that bin Laden was unarmed but put up resistance.
Many believe American Special Forces could have arrested the al-Qaeda leader without having to kill him and a question raised is why bin Laden's body was buried at sea so soon after his death.
A US official says bin Laden's body has been buried at sea, alleging that his hasty burial was in accordance with Islamic law, which requires burial within 24 hours of death.
This is while burial at sea is not an Islamic practice and Islam does not determine a timeframe for burial.
