Gulf Cooperation Council (GCC) countries held an extraordinary meeting on Saturday, over Saudi-Iran tension condemning, Iranian interference in Saudi Arabian domestic affairs amid high tension between the two countries.
Diplomatic relations between the two regional rival states were cut after protesters attacked the Saudi embassy in Tehran on Sunday following the execution of a Shiite cleric as well as 46 others on “terrorism” charges in Saudi Arabia on Saturday.
"The ministerial council strongly denounced these acts by Iran and stated that Iran carries the responsibility for these terrorist acts," the GCC said in a statement after an extraordinary meeting in Riyadh.
Saudi Arabia's foreign minister, Adel al-Jubeir said on Saturday that his country was looking forward to add additional measures against Iran.
His comments were made known at a press conference following the GCC extraordinary meeting.
Jubeir also said Saudi Arabia has called upon the Organisation of Islamic Cooperation to convene an extraordinary meeting over Iran’s storming into the Saudi Embassy.
Iran's foreign minister, Mohammad Javad Zarif complained about Saudi Arabia's "provocations" against Tehran in a letter to the UN Secretary-General Ban Ki-moon, Iranian media outlets published earlier on Saturday.
Official from the UN, US, Turkey and EU called on both sides to ease the tension.
Iran and Saudi Arabia, which consider each other as regional rivals, have already been at odds over the civil wars in Yemen and Syria as they support opposing sides.
