In Mahmoud Ahmadinejad's latest verbal assault on Israel, the Iranian president said it would soon "fade away from the earth."

"The crimes being committed by the Zionist regime [Israel] are happening because it is aware that it has reached the end of the line and will soon fade away from the earth," Mehr news agency quoted Ahmadinejad as saying during an anti-Israeli rally in Tehran.

He said world powers have become increasingly hesitant to show further support for Israel, which he said has lost direction.

Ahmadinejad claimed that Israel's "crimes" in Gaza were aimed at changing the political leaders in the troubled region in line with its own political interests.

Israel has enforced a blockade on the Gaza Strip since the Islamist organization Hamas seized power there in June 2007.

The Iranian president has attracted international condemnation in the past three years with his attacks on Israel, suggesting it should be "wiped off the map."

However, he has repeatedly rejected charges he is anti-Semitic.

Iran does not acknowledge the sovereignty of Israel and supports the Hamas rule in the Gaza Strip.

At the Friday prayer ceremony in Tehran, the Iranian cleric Ahmad Khatami condemned international organizations and even Arab countries, including Egypt, for having remained silent over the situation in Gaza.
