Ilich Ramírez Sánchez is a convicted Venezuelan terrorist and murderer. After several bungled bombings, he achieved notoriety for a 1975 raid on the OPEC headquarters in Vienna, resulting in the deaths of three people. For many years he was among the most wanted international fugitives. He is now serving a life sentence in La Santé Prison in Paris for the murder of two French agents of the DST and an alleged informant. Ramírez Sánchez was given the nom de guerre Carlos when he became a member of the leftist Popular Front for Liberation of Palestine. Carlos was called the "Jackal" by The Guardian when Frederick Forsyth's novel The Day of the Jackal was found among his belongings.
