Following on what the Coalition had previously announced regarding the ballistic missiles launched by the Iranian-controlled Houthi militias from within Yemeni territory that targeted the Kingdom of Saudi Arabia, the most recent of which was the flagrant military aggression by the Iranian-controlled Houthi militias which targeted the city of Riyadh on November 04, 2017 (Corresponding to 15/2/1439 Hijri) using a ballistic missile with a range of more than 900 Km. And, after the thorough examination of the debris of these missiles, including the missile launched on July 22, 2017 (Corresponding to 28/10/1438 Hijri) by experts in military technology, has confirmed the role of Iran's regime in manufacturing these missiles and smuggling them to the Houthi militias in Yemen for the purpose of attacking the Kingdom, its people, and vital interests. The Coalition's command considers the Iranian regime's action in supplying the Houthi militias that it commands with these missiles to be a blatant violation of the United Nations Security Council (UNSC) Resolutions that prohibit nations from arming these militias, specifically UNSC Resolution (2216). Further, Iran's role and its direct command of its Houthi proxy in this matter constitutes a clear act of aggression that targets neighboring countries, and threatens peace and security in the region and globally. Therefore, the Coalition's Command considers this a blatant act of military aggression by the Iranian regime, and could rise to be considered as an act of war against the Kingdom of Saudi Arabia, and thus affirms the legitimate right of the Kingdom to defend its territory and people in accordance with Article (51) of the U.N. Charter. The Coalition Command also affirms that the Kingdom reserves its right to respond to Iran in the appropriate time and manner, in accordance with international law and based upon the right of self-defense, including the defense of its territory, its people, and its vital interests, which is enshrined in international agreements and conventions including the UN Charter. To address the vulnerabilities in the current inspection procedures that led to the continuation of the supply of ballistic missiles and military equipment to the Houthi militias which enabled them to continue to commit crimes against the Kingdom, the Yemeni people, and the peoples of countries in the region, which constitutes blatant violations to international humanitarian laws, the Coalition's Command has decided to temporarily close all Yemeni ground, air, and sea ports. These measures will be implemented while taking into consideration the continuation of the entry and exit of humanitarian supplies and crews in accordance with the Coalition's updated procedures. The Coalition Command calls upon all relevant parties to adhere to the inspections, entry, and exit procedures to and from Yemeni ports of entry designated by the Coalition that will be announced later. All necessary legal steps will be taken against violators of these procedures. The Coalition Command calls upon the brethren Yemeni people and all civilian and humanitarian crews to avoid areas of combat operations, areas populated by the Houthi armed militia, areas and ports exploited by this Iranian-controlled militia to smuggle weapons, and areas from which this militia launch its attacks against the Kingdom. The Coalition also calls upon diplomatic missions to avoid areas that are not controlled by the Legitimate Government of Yemen. The Coalition Command calls upon the international community and the United Nations Security Council including the sanctions committee established by the Council for the implementation of UNSC Resolution 2216, to take all necessary legal measures to hold Iran accountable for its violation of UN Security Council Resolutions, primarily resolution 2216, in addition to its violations of provisions and principles of international law that criminalize the aggression against other states, due to: Iran's direct involvement in the unlawful smuggling of weapons to the Houthi Militia under its control, which threatens international peace and security; its aggression against the territory and people of Saudi Arabia and other neighboring countries; and its continued support for the Houthi militia in violation of international resolutions that aim to restore legitimacy in Yemen.
