A terrorist-turned-informant who helped plan the 2008 Mumbai attacks testified in court that a Pakistani intelligence officer worked with militants to get financing for his anti-India terrorist group. American-born David Coleman Headley is a witness in the trial of Tahawwur Rana, a Chicago businessman accused of aiding the Mumbai attacks, and is likely to further inflame U.S.-Pakistani relations that have been strained since Osama bin Laden's death. U.S. officials believe someone must have been aiding the al-Qaida leader at his compound in Abottabad, where he successfully hid for a decade. Pakistan has denied any knowledge of his whereabouts and Secretary of Defense Robert Gates said there is no evidence that an aid or aids were on the inside. But some American lawmakers remain suspicious of Pakistan's government.
