"Funding Bin Laden:
Ken Timmerman said, Iran had business ties with Osama Bin Laden going back to the early 1990's. This document, presented by the Iranian People's Fedaii Guerrillas to the United Nations Security Council in 1996, it is a wire credit advice on an Iraqi oil shipment to Iran and details the purchase of oil products smuggled through Iran by Iranian Revolutionary Guards in violation of the UN Sanctions. They took delivery of the oil in small coastal tankers to avoid interception by the US-led naval blockade, then turned it around and resold it. The final purchaser was the Al Shamal Islamic Bank in Sudan, Bin Laden's own bank."
