A casino in Argentina apparently played a key role in disrupting an alleged money laundering ring connected to Islamic militant group Hezbollah.

This week, Argentine media reported that police had raided a number of casinos and hotels in Puerto Iguazú, near the ‘triple frontier’ intersection of the borders of Argentina, Brazil and Paraguay. The raids were part of an ongoing investigation into the activities of Assad Ahmad Barakat, a Lebanese national with alleged ties to Hezbollah.

Last month, Argentina’s Financial Information Unit (UIF) froze the assets of Clan Barakat, a group associated with Assad, who has been designated a terrorist financier by the US Office of Foreign Assets Control (OFAC).

Barakat and 13 other individuals linked to the Clan reportedly paid hundreds of visits to Casino Iguazú over the past few years. One Clan member, Assad’s cousin Hassan Ali Barakat, reportedly made 620 border crossings during that span. All of the individuals cited in the reports reside in either Brazil or Paraguay and none appears to have any business interests in Argentina.
