The commission's report says bin Laden "explored possible cooperation with Iraq during his time in Sudan, despite his opposition to [Saddam] Hussein's secular regime. Bin Laden had in fact at one time sponsored anti-Saddam Islamists in Iraqi Kurdistan.
"The Sudanese, to protect their own ties with Iraq, reportedly persuaded bin Laden to cease this support and arranged for contacts between Iraq and al Qaeda."
A senior Iraqi intelligence officer reportedly made three visits to Sudan, finally meeting bin Laden in 1994.
Bin Laden is said to have requested space to establish training camps, as well as assistance in procuring weapons, but Iraq apparently never responded.
"There have been reports that contacts between Iraq and al Qaeda also occurred after bin Laden had returned to Afghanistan, but they do not appear to have resulted in a collaborative relationship," the report said.
"Two senior bin Laden associates have adamantly denied" any relationship, the report said.
