Eighty-five people were killed in Buenos Aires in July 1994, when a truck filled with explosives detonated outside the Jewish Argentine Mutual Association (AMIA). Since then, conspiracy theorists have had a field day speculating about who was responsible, but it is generally believed to have been the work of Hezbollah, the Iran-backed Lebanese militia group listed on the U.S. State Department's list of foreign terrorist groups. The presence of Islamist militants, including Hezbollah, in South America—in particular, in the anarchic Tri-border Region, where Brazil, Argentina, and Paraguay meet—has long been suspected. According to the Los Angeles Times, though, terrorism analysts fear that Hezbollah is expanding its base in Venezuela.
Hugo Chavez's government enjoys warm relations with Iran, Hezbollah's financial and ideological patron. The countries have established numerous business ties, and in March 2007 agreed to flights between their capitals on IranAir—flights that include a layover in Damascus. (The State Department complained early on that passengers arriving in Caracas seldom were checked against immigration databases or had their passports stamped. Venezuela has reportedly stepped up security procedures as a result.) In June, the US government accused two Venezuelans of working with Hezbollah, obtaining finances and arranging travel. Such activities may represent things to come.
