Abdulfattah gave birth to four children by bin Laden while in Pakistan -- two in a government hospital in Haripur and two further children in Abbottabad.

She is now being held by Pakistani authorities in a house in Islamabad alongside two of bin Laden's other wives.

The widows, and two of bin Laden's daughters -- Maryam, 21, and Sumaya, 20 -- are expected to be charged Monday with breaking Pakistan's immigration laws. The offense carries a possible five-year jail sentence.

An editorial published in the Dawn newspaper Friday said Abdulfattah's testimony should force Pakistan to "take a long, hard look at its record against terrorism."

"For nine years the world's most wanted terrorist survived in the country after fleeing the U.S. attack on Tora Bora [in December, 2001]," it said.

"What is clear is that the judicial commission looking into his presence and the raid in Abbottabad can no longer limit its probe to those topics. In light of this investigation report, the commission now needs to expand its focus to encompass bin Laden's presence in the country since 2002," it added.
