Iran is actively wreaking havoc across the Middle East, a group of 11 Arab nations declared in a letter sent recently to outgoing UN Secretary-General Ban Ki-moon.

“It is with a deep sense of frustration that we note that the Islamic Republic of Iran, with its expansionist regional policies, flagrant violations of the principle of sovereignty and constant interference in the internal affairs of Arab States, continues to play a negative role in causing tension and instability in our region,” the letter — signed by the UN envoys of Bahrain, Egypt, Jordan, Kuwait, Morocco, Oman, Qatar, Saudi Arabia, Sudan, United Arab Emirates and Yemen — said.

Furthermore, the Arab UN representatives expressed “concerted alarm” at Tehran’s promotion of “the export of its revolution to other countries.”

“We stress that the Islamic Republic of Iran is a state sponsor of terrorism in our region, from Hezbollah in Lebanon and Syria, to Houthis in Yemen and terrorist groups and cells in the Kingdom of Bahrain, Iraq, the Kingdom of Saudi Arabia, Kuwait and elsewhere,” the letter stated.

Since the signing of the nuclear deal by Iran and six world powers in July 2015, the letter noted, “we have seen nothing but increased Iranian aggression in the region and the continuation of support for terrorist groups.”

“We remain firm in our resolve that any interference by the Islamic Republic of Iran in the domestic affairs of Arab states is unacceptable and must be confronted,” the letter stated. “[T]he only way forward is for the Islamic Republic of Iran to comprehensively change its foreign policies and end hostilities, thus paving the way for the region to enter a new era of stability and development.”

UN Watch — a Geneva-based watchdog NGO that monitors the activities of the global intergovernmental organization — praised the letter, which was dated October 31.

“Iran likes to dismiss all criticism of its human rights violations and brutality at home and abroad as part of a Western plot, but that’s hard to sustain when the accusers are all Muslim governments, including recent allies of Iran like Sudan,” UN Watch Executive Director Hillel Neuer said in a statement.

As reported by The Algemeiner, a top Iranian official vowed in September that Tehran’s backing of “resistance groups” in the Middle East would remain steadfast.

When Iranian regime officials speak of “resistance groups,” they are generally referring to Tehran-supported terrorist organizations, such as Hezbollah and Hamas. The term is also used by Iran to describe the Houthis in Yemen, who are receiving Iranian aid as they battle for control of that southern Arabian Peninsula country against the Saudi-backed government of Yemeni President Abd Rabbuh Mansur Hadi.

In his UN General Assembly speech in September, Israeli Prime Minister Benjamin Netanyahu said that in addition to Egypt and Jordan, which already have signed peace treaties with Israel, “Many other states in the region recognize that Israel is not their enemy. They recognize that Israel is their ally. Our common enemies are ISIS and Iran. Our common goals are security, prosperity and peace. I believe that in the years ahead we will work together to achieve these goals.”
