In February 1979, Palestine Liberation Organization chairman Yassir Arafat, arch-foe of the Israeli rulers, was welcomed to Tehran by the Iranian revolutionaries as the first foreign "head of state" to visit them. The historical irony was manifest: Arafat was treated as a hero in the same land that had supplied much of Israel's oil; the country where Israelis had participated in training the SAVAK, the Shah's secret police; and where both Israeli and Iranian pilots had trained on U.S.-supplied Phantom F-4 fighter-bombers. Arafat announced that the Ayatollah Khomeini has assured him that Iran's revolution would be incomplete until the Palestinians won theirs. Within weeks, the PLO had installed a mission in the former Israeli embassy in Tehran, as well as in Ahwaz and Khorramshahr, in the heart of the Iranian oil province, selecting as its Tehran representative Hani al-Hassan, of al-Fatah's conservative "Muslim" wing, in a move obviously designed to appeal to the Ayatollah.
