Following the Iranian Revolution and the fall of the Pahlavi dynasty in 1979, Iran adopted a sharp anti-Israel stance. Iran cut off all official relations with Israel; official statements, state institutes, and events. Iran ceased to accept Israeli passports, and the holders of Iranian passports were banned from travelling to "the occupied Palestine"’ The Israeli Embassy in Tehran was closed and handed over to the Palestinian Liberation Organisation. Ayatollah Khomeini declared Israel an "enemy of Islam" and 'The Little Satan'—the United States was called 'The Great Satan'.
