The United States imposed on Friday sanctions on a senior Hezbollah operative for his involvement in the 1994 bombing of a Jewish community center in Argentina’s capital Buenos Aires. In a statement, the State Department also offered a $7 million reward for information on the whereabouts of Salman Raouf Salman, also known as Samuel Salman El Reda, who it said helped plan and carry out the attack in Argentina that left 85 people dead. A US administration officials said they believed Salman was in the Middle East. The announcement follows the arrival of US Secretary of State Mike Pompeo in Buenos Aires for a regional security conference. During his visit, Pompeo will highlight the risks posed by Hezbollah, US officials said. The Iran-backed, party is part of Lebanon’s coalition government. Argentinian authorities on Thursday designated Hezbollah, which it blames for the attack on the Jewish community center and an attack on the Israeli embassy in Buenos Aires in 1992 that killed 29 people. “We are targeting Salman Raouf Salman, who coordinated a devastating attack in Buenos Aires, Argentina against the largest Jewish center in South America 25 years ago and has directed terrorist operations in the Western Hemisphere for Hezbollah ever since,” said Sigal Mandelker, the US Treasury’s undersecretary for terrorism and financial intelligence. The sanctions will freeze any assets belonging to Salman in the United States and prohibits US citizens from dealing with him.
