Haniffa Bin Osman has told US undercover agents in July 2006 that the weapons were to be sent for the use by the LTTE who are fighting against the Sri Lankan forces.

"On August 1, 2006, Osman told the undercover agents that the Tamil Tigers wired a deposit of $250,000 as a down payment for the purchase of the weapons. Indeed, the next day $250,000 was wired from Malaysia to an undercover bank account in Maryland," the statement said.

The United States designated the LTTE as a Foreign Terrorist Organization in1997. The LTTE is also banned as a terrorist outfit in India, Canada and within the EU.

Thirunavukarasu Varatharasa, a Sri Lankan, Subandi, an Indonesian national, Wotulo, 60, an Indonesian and a retired Indonesian Marine Corps General were already imprisoned in the US for their parts in the operation.
