The Foreign Ministry said in a statement that it didn't trust a recent assessment made by the U.S. Department of Treasury regarding money allegedly being raised in the region where Argentina, Brazil and Paraguay meet, to fund Lebanon's Hezbollah.
Earlier this week, the U.S. Treasury Department identified nine individuals and two groups that have provided "financial and logistical" support to Hezbollah.
All those named are located in the Tri-border area -- which has long been suspected of being a center of finance for Hezbollah.
Among those named is Assad Ahmad Barakat, who in June 2004 was accused of heading a support network for Hezbollah.
"Assad Ahmad Barakat's network in the Tri-border area is a major financial artery to Hezbollah in Lebanon," said Adam Szubin, director of the Office of Foreign Assets Control. "Today's action aims to disrupt this channel and to further unravel Barakat's financial network."
