The Assassination of Orlando Letelier was a car bombing which killed Orlando Letelier, a Chilean socialist political figure when Salvador Allende was president of Chile. It all starts when he was based in the United States as an activist. Letelier was killed in Washington, D.C. with his American assistant, Ronni Karpen and her husband, Michael Moffitt (who worked for Letelier) by some Chilean DINA agents in September 21, 1976. Until 9/11, it was known as the most infamous act of international terrorism in the capital of the US.
