Jerusalem Day is an annual event initiated by revolutionary Iran's spiritual and political leader Ayatollah Khomeini as a show of solidarity with the Palestinian Arabs in their struggle against Israel. He called for all the Muslims of the world and the Muslim governments to join together to support legitimate rights of the Palestinian people against Israel. Jerusalem Day is marked annually on the fourth Friday of the month of Ramadan.
The day on which Israelis and Jews throughout the world commemorate the reunification of the city of Jerusalem during the Six-Day War (1967). On 7 June 1967, an Israel Defense Forces paratroop brigade led by Mordechai (Motta) Gur captured the walled city and East Jerusalem, those areas held by Jordan since the end of the War of Independence (1948—49) and from which Israelis had been denied access (in violation of the 1949 armistice agreement). Gur's brief report, "The Temple Mount is in our hands," became a major element of the Israeli national psyche. Yom Yerushalim is commemorated each year on the 28th day of the month of Iyar.
