Iranian President Mahmoud Ahmadinejad on Sunday said that the existence of "the Zionist regime" is an insult to humanity, according to Iranian news agency IRNA.

Ahmadinejad made his remarks at a conference called "National and Islamic Solidarity for the Future of Palestine" where he declared Israel the reason for instability in the Middle East.

The Iranian leader said Israel's presence on even one inch of the region's soil was a cause for crisis and war, adding that the only way to confront Israel is through the resistance of Palestinian youth and other nations in the region.

Ahmadinejad also told the conference that the "Zionist regime" is the origin of all the wars, genocide, terrors and crimes against humanity and that it is a racist group that does not respect human principles.

Also in attendance at the conference were Hamas Chief Khaled Meshal, Islamic Jihad leader Ramadan Abdullah Shallah and the head of the Popular Front for the Liberation of Palestine General Command, Ahmed Jibril, all of whom live in exile.

The Iranian president ended his speech by suggesting a referendum on the destruction of Israel.
