After the U.S. Congress prohibited federal funding of the contras in 1983, the Reagan administration nonetheless illegally continued to back them by covertly selling arms to Iran and channeling the proceeds to the contras (the Iran–Contra affair), for which several members of the Reagan administration were convicted of felonies. The International Court of Justice, in regard to the case of Nicaragua v. United States in 1984, found, "the United States of America was under an obligation to make reparation to the Republic of Nicaragua for all injury caused to Nicaragua by certain breaches of obligations under customary international law and treaty-law committed by the United States of America". During the war between the contras and the Sandinistas, 30,000 people were killed.
