Press TV - Iran has rejected recent unfounded and hackneyed allegations made by Saudi Foreign Minister Adel Ahmed al-Jubeir against Tehran, saying Riyadh is undoubtedly the most infamous sponsor of terrorism in the world.

"The root cause of terrorism that has engulfed the entire world, particularly the Middle East, is nowhere but Saudi Arabia and the radical thoughts and ideologies that are promoted, spread and financed by this regime," Iranian Foreign Ministry Spokesman Bahram Qassemi said on Saturday.

Addressing the 73rd annual session of the United Nations General Assembly in New York on Friday, Jubeir once again repeated his anti-Iran rhetoric and claimed that Tehran was continuing its �terrorist activities and hostile behavior� and added that peace and stability in the Middle East requires �deterring Iran�s expansionist and subversive policies.�

He also said Saudi Arabia supports US President Donald Trump�s new strategy �in dealing with Iran."

In response to Jubeir's claims, the Iranian spokesperson said it is no surprise that the Saudi foreign minister proudly expresses his country's support for Trump's strategy to counter multilateralism and undermine international agreements and accords as Saudi Arabia has been among the most important supporters of a current affiliated with Trump's thoughts in the US which, along with the Zionist lobby and the United Arab Emirates, is spending billions of dollars to promote Washington's warmongering and its policy of destabilizing other parts of the world.

Jubeir leveled the accusations against Iran on the same day that the US hosted a meeting of top Arab diplomats in New York to push forward a plan to establish a NATO-like regional alliance to confront Iran.

The US State Department said in a statement that the participants in the meeting had all underlined "the need to confront threats from Iran directed at the region and the United States."
