Large crowds took to the streets in the capitals of Iran, Iraq and Yemen for the annual show of support for Palestinians and denunciation of Israel.
Quds (Jerusalem) Day commemorations were launched in 1979 by Ruhollah Khomeini, the founder of the Islamic republic, which has made support for the Palestinian cause a cornerstone of its foreign policy.
The marches, which call for Jerusalem to be returned to the Palestinians, are traditionally held on the last Friday of the Muslim holy month of Ramadan. Crowds gathered in the streets of Tehran after supreme leader Ali Khamenei urged the Iranian people to protest against "the enemies' tricks".
