Four international experts have commenced work in Riyadh, Buqayq and Khurais to investigate the evidence and used weapons in Aramco attacks. They would conclude their visit on Sunday or Monday. Saudi Arabia has informed the 15 members at the Security Council in addition to Secretary-General Antonio Guterres that it will take all necessary measures according to the international law to deal with the targeting of Aramco facilities. Permanent Representative of Saudi Arabia to the United Nations Abdullah al-Moallemi sent a letter to the President of the Security Council and Russia’s Permanent Representative to the UN Vasily Nebenzya, upon the Saudi government’s guidelines. The purpose of the letter is to draw the attention regarding the terrorist attack against Aramco facilities in Buqayq and Khurais on Sep. 14, 2019. Moallemi noted that the attacks didn’t target the Kingdom only, but the international energy supplies and the global economic security, affirming that Saudi Arabia has the capability to protect its vital economic and oil assets as well as its national possessions, residents, and citizens. The letter stated that “all indications are that the weapons used in the Aramco attack are Iranian,” and stressed that Saudi Arabia will take measures to respond to the attacks in accordance with international law. It also included a statement issued earlier by the Saudi Interior Ministry on Sep. 16 calling for the UN and international experts to participate in the investigation into the attack. Further, reliable sources told Asharq Al-Awsat newspaper that the experts group consists of Christina George and Rob LaFeber from the committee entrusted with United Nations Security Council Resolution 2231 on the nuclear program of Iran and Wolf Christian Pace and Henry Thompson from the 2140 Yemen Sanctions Committee. The team would visit the facilities on Friday and Saturday, and its mission includes examining ruins of drones and the used cruise missiles in the attacks.
