United States (U.S.) want to check out the three widows of Osama bin Laden and intelligence material left behind by the commandos at the hideout of Al-Qaeda's leader. They are now in Pakistani custody.

According to the Associated Press, the women were reportedly stayed at home after U.S. commandos killed bin Laden in their home in Abbottabad, Pakistan, May 1 last. They might be able to answer the question whether Pakistan protecting al-Qaeda leaders, as many U.S. officials suspected.

This examination can also reveal the daily life of bin Laden, what he's doing since the U.S. invaded Afghanistan in 2001 and activities of al-Qaeda.

Together with their children, the women were believed to have been in the custody of Pakistan army. So says the U.S. National Security Advisor, Tom Donilon, the talk show "Meet the Press" on NBC stations.

CIA and Pakistani intelligence agency, known by the acronym ISI, have cooperated closely in the past to memeragi terrorism. However, unilateral U.S. attack on bin Laden - who carried out without the knowledge of Pakistan - has led to estrangement relationship between the two governments.

Pakistan was offended because the area has become a target of U.S. military operations. Instead, Washington suspicious because some Pakistani security forces and intelligence actually already knew about bin Laden's hideout, but let it go and sympathize with him.
