The rallies are held to mark Quds Day, which falls on the last Friday of the Muslim fasting month of Ramadan.
In Tehran and other cities and towns, people from all walks of life are gathering for the annual event which usually markschantingslogans against Israel and burning itsflags.
The occasion is a legacy of the late founder of the Islamic Republic Imam Khomeini, followed by Muslims inother countries to support the Palestinian struggleagainst Israel.
On Wednesday, Leader of the Islamic Revolution Ayatollah Seyyed Ali Khamenei emphasized the importance of Quds Day.
It is not just that we are defending an oppressed nation that has been driven out of its home. We are actually fighting against an oppressive and arrogant political system, Ayatollah Khamenei said.
Half a century of occupation
Earlier this month, Palestinians marked the 50th anniversary of the 1967 Six-Day War, which saw Israel occupy the West Bank, East Jerusalem al-Quds, the Gaza Strip and part of Syrias Golan Heights.
In November that year, the UN Security Council adopted Resolution 242, under which Israel is required to withdraw from all territories seized in the war.
Tel Aviv withdrew from Gaza in 2005, but has been keeping the coastal enclave under a crippling siege and regular deadly offensives. The regime has also been expanding settlements across the West Bank and East Jerusalem al-Quds in breach of international laws.
The global protests this year coincide with stepped-up killing of Palestinians, their forced displacement and abusive detention by Israel.

In the early hours of Friday, Bahraini people held anti-Israel rallies in different areas to commemorate Quds day.
