Iran's Supreme Leader Ayatollah Ali Khamenei said in his Eid al-Fitr sermon on Sunday that the high turnout of Quds Day rallies in Iran were "a loud and clear shout against the cancer of Zionism."

Millions of Iranians took to the streets on Friday in different cities to mark the annual anti-Israel Quds Day march in solidarity with Palestinians.

Khamenei said the Quds Day rallies proved once again that the Islamic world does not accept tyranny and the West has failed to undermine Muslims' unity, Iran's English-language satellite channel Press TV reported.

The massive rallies were indicative of the fact that those "conspiracies of the arrogant powers" to weaken the Quds Day among Muslims in recent years were "futile", Khamenei said on the occasion of the Eid al-Fitr, a Muslim holiday that marks the end of the holy fasting month of Ramadan.

On Friday's rallies, a statement was issued in support of Palestinians, which said that the Iranians "support Palestinian resistance and Israel must avoid any new adventurism" in the region.

Iranian President Mahmoud Ahmadinejad addressed a crowd gathered at Tehran University at the end of the rallies, reiterating that the Holocaust was a "myth" created by the West to support Israel.

"They (the West) created the myth of the Holocaust," Ahmadinejad said. "They lied and then support the Jews," he added.
