"Akhtar was adept at getting CIA cash into the hands of Afghan jihadists," read the report into investigation of leaked accounts.

Former senator Haroon's brother, who did not want to be named, told Dawn "that none of the countries that funded the war in Afghanistan had ever accused his late father of misappropriation."
