TEHRAN -- Supreme Leader of the Islamic Revolution Ayatollah Seyyed Ali Khamenei stated here on Tuesday that the Zionist regime poses a major threat to the Muslim world.

“One day regional nations will definitely witness the destruction of the Zionist regime,” but the Muslim countries’ actions will determine when it happens, Ayatollah Khamenei said at a meeting with Mauritanian President Mohamed Ould Abdel Aziz.He praised Mauritania for severing ties with Israel and said certain Arab states should learn a lesson from Mauritania’s move because Israel poses a serious threat to the Muslim world and is seeking to dominate the region.Mauritania suspended its diplomatic ties with Israel in January 2009 in protest over Israel’s war on Gaza. It closed the Israeli embassy in March 2009.The Supreme Leader said cooperation with Islamic countries is a principle of Iran’s foreign policy and expressed hope that the Mauritanian president’s trip to Iran would pave the way for the expansion of relations between the two countries.Ayatollah Khamenei also called for unity among Islamic countries.Genuine unity and brotherhood among Islamic countries should be established so that the Islamic ummah (community) will attain their rightful place, the Supreme Leader added.The Mauritanian president said that the Muslim world is proud of Iran’s industrial, technological, and scientific advancements and called for closer ties between Tehran and Nouakchott.He also thanked the Islamic Republic for its efforts to establish peace in the region and in the rest of the world
