The United States military attempted a rescue operation, Operation Eagle Claw, on April 24, 1980, which resulted in an aborted mission and the deaths of eight American military men. The crisis ended with the signing of the Algiers Accords in Algeria on January 19, 1981. On January 20, 1981, the date the treaty was signed, the hostages were released. The Iran-United States Claims Tribunal (located in The Hague, Netherlands) was established for the purpose of handling claims of American nationals against Iran and of Iranian nationals against the United States. American contact with Iran through The Hague covers only legal matters. The crisis led to lasting economic and diplomatic damage.
