ISLAMABAD -- Pakistani Prime Minister Syed Yusuf Raza Gilani constituted the commission for investigation into the presence of Osama bin Laden and the US Special Forces operation in the city of Abbotabad to kill the al-Qaida chief, officials said Wednesday.

The five members commission will be headed by judge of the Supreme Court of Pakistan, Justice Javed Iqbal, officials from the Prime Minister office said.

The commission is mandated to ascertain the full facts regarding the presence of Osama bin Laden in Pakistan. It will investigate circumstances and facts regarding US operation in Abbotabad on May 2.

The commission shall determine the nature, background and causes of lapses of the concerned authorities, if any, and it shall make consequential recommendations.

The Secretary Cabinet will work as Secretary of the Commission.

It was not specified when the commission will submit report.

The opposition parties had been asking for formation of judicial commission to investigate the whole episode of the US unilateral operation in Pakistan to kill bin Laden.

Pakistan has also been under mounting US pressure to investigate as to who facilitated the al-Qaida chief to live in the Pakistani garrison city.

US Secretary of State Hillary Clinton, who traveled to Islamabad on Friday, said that no Pakistani at the highest level knew about the presence of Osama bin Laden in Abbotabad but insisted that Pakistan should investigate his supporting network.
