Iranian President Mahmud Ahmadinejad also addressed the conference, saying that the existence of Israel poses a threat to the Islamic world. He called Israel a "rotten, dried tree" that will be annihilated by "one storm".
The conference is being attended by some 600 delegates from more than 20 countries including Syria, Jordan, Lebanon, and Russia.
Representatives of the militant groups Hamas, Hezbollah and the Islamic Jihad are reportedly also in attendance at the three-day conference.
