WASHINGTON Pressured by increased scrutiny of terrorist money sources and strikes aimed at its financiers, Qaedas core organization has turned to kidnapping for ransom in Pakistan to offset dwindling cash reserves, the USA today said quoting US officials and information in files retrieved from Osama bin Ladens compound. Bin Ladens interest in kidnapping as a cash-raiser bolsters accounts that the financial squeeze has staggered Qaeda, forcing it to search for alternative funding sources. Officials would not detail Qaedas role in specific crimes, but the groups affiliates have targeted diplomats, tourists and merchants. His awareness of Qaedas growing use of kidnapping is evidence that even in isolation behind high walls in Abbottabad, bin Laden kept tabs on how his network moved its money. Experts from the CIAs National Counterterrorism Center, the Treasury Department and the FBI and military are trying to learn more from the recovered files about Qaedas money sources and the impact of bin Ladens death on the groups financial future. They hope to identify important Qaeda donors, especially wealthy Persian Gulf figures. The Treasury Departments acting undersecretary for terrorism and financial intelligence, David Cohen, said US efforts are focused on disrupting Qaedas cash flow from donors, fundraisers and facilitators. Qaedas supporters ought to be wondering if their identities have been revealed, Cohen said. Analysts are examining lists of numbers found in bin Ladens files, hoping to find bank accounts, credit cards or ledgers depicting the financial underpinnings of network known to demand strict accounting from its operatives. Qaedas leadership inside Pakistan rarely championed kidnappings publicly and was not known previously to widely support its use as a funding source. The group historically relied on donations through a pipeline of couriers and money-changing operations. At the time of the Sept. 11 attacks, the network took in as much as $30 million annually, but that money flow has tightened, said Rep.
