The complete story:
Last February, the Obama administration accused one of Lebanon’s famously secretive banks of laundering money for an international cocaine ring with ties to the Shiite militant group Hezbollah.
Now, in the wake of the bank’s exposure and arranged sale, its ledgers have been opened to reveal deeper secrets: a glimpse at the clandestine methods that Hezbollah — a terrorist organization in American eyes that has evolved into Lebanon’s pre-eminent military and political power — uses to finance its operations. The books offer evidence of an intricate global money-laundering apparatus that, with the bank as its hub, appeared to let Hezbollah move huge sums of money into the legitimate financial system, despite sanctions aimed at cutting off its economic lifeblood.
At the same time, the investigation that led the United States to the bank, the Lebanese Canadian Bank, provides new insights into the murky sources of Hezbollah’s money. While law enforcement agencies around the world have long believed that Hezbollah is a passive beneficiary of contributions from loyalists abroad involved in drug trafficking and a grab bag of other criminal enterprises, intelligence from several countries points to the direct involvement of high-level Hezbollah officials in the South American cocaine trade.
