ISLAMABAD: A doctor charged in the United States with working for Pakistan's spy agency to influence American lawmakers on their policy toward the disputed Kashmir region has died in Islamabad after suffering a stroke.

Dr Zaheer Ahmed was one of two people accused in the case, which has complicated strained relations between Pakistan and the United States.

Hospital spokesman Azmatullah Qureshi said Ahmed died Friday after a stroke on September 28.

US prosecutors accused Ahmed of recruiting people to act as straw donors who would give money to a pro-Kashmir group in Washington that really was coming from the Pakistani government.

Ahmed was not arrested in Pakistan and never commented on the allegations. He had dual US and Pakistani citizenship.
