In January 1988, during the First Intifada, the Jerusalem Committee of the Organization of the Islamic Conference decided that Quds Day should be commemorated in public events throughout the Arab world. In countries with significant Shia Muslim populations, particularly Lebanon, where Hezbollah organizes Quds Day observances, there is significant attendance at the day’s events. Events are also held in Iraq, the Palestinian Gaza Strip, and Syria. Both Hamas and Palestinian Islamic Jihad endorse Quds Day and hold ceremonies.
