Iranian senior diplomat has warned that interference in the internal affairs of other countries, occupation and extremism threaten the world peace, security and development.

The Iranian Foreign Minister Mohammad Javad Zarif said on Thursday: "It is evident that Intervention, invasion and occupation as in the cases of Iraq, Syria and Palestine, leads to extremism. The tragedy of Palestine, the center of anger and desperation felt in the Muslim world, is at the heart of this crisis."

Speaking at the foreign ministerial meeting of the Non-Aligned Movement (NAM) in Venezuela’s Margarita Island, Zarif said, "In such a difficult and challenging situation, self-restraint and full commitment to international law, regulations and norms in addition to UN Charter principles are a matter of absolute necessity.”

“Violent extremism and terrorism accompanied by their horrific consequences, like growing hostilities and humanitarian crises, are among the gravest threats that require more serious attention from NAM member states,” he added.

The 17th Non-Aligned Movement (NAM) summit began on September 15 in Margarita Island, Venezuela, and will continue until September 18.

The NAM started at the height of the Cold War as different countries were seeking to be independent from the US and the former Soviet Union. The Non-Aligned Movement's countries are overwhelmingly developing countries in the Middle East, Africa, Asia, and Latin America.

The last Non-Aligned Movement summit was hosted by Iran in 2012.
