An alleged financier for Hezbollah, Assad Ahmad Barakat, was arrested in Brazil, accused of laundering $10 million at a casino in Argentina. In 2004, the US Treasury said Barakat was one of the most influential members of  Hezbollah, a listed terrorist organization. It accused him of using his businesses in the border areas of Brazil, Paraguay and Argentina as a front for fundraising for Hezbollah as well as coercing local shopkeepers into giving money to the organization. Barakat is on the US sanctions list.
Paraguay has stated that it believes Barakat financed the 1994 attack in Buenos Aires that killed 85 people.
