Yemenis launched a solid propellant and scud-type missile against the international airport of King Khalid which is located thirty-five kilometers north of Riyadh as the capital of Saudi, in reaction to Saudi Arabia's devastating aerial bombardment campaign over Yemenis. Abdul-Malik al-Houthi declared that they are aware that what (targets) could cause big trouble and of course how to reach them. The leader of Ansar Allah emphasized that Saudi Arabia and UAE are within range of the missiles, and Yemeni's UAVs will begin bombing the targets over Saudi Arabia. Abdul-Malik al-Houthi also warned the companies and investors who are in UAE that all companies in UAE ought not to consider United Arab Emirates as a safe country from now on. He also said to invaders that they ought not to commit aggression to Al-Hudaydah if they want to protect their oil tankers. Legal background According to the international law of naval blockade the naval measures conducted by the coalition led by Saudi Arabia do not amount to a naval blockade in the legal sense. It is said that neither the international law of contraband nor the United Nations Security Council Resolution 2216 of 14 April 2015 cover the extensive enforcement measures. Due to the devastating famine in Yemen and supply shortage of essential goods, which are caused by the enforcement measures, the naval operations off the coast of Yemen are criticized as a violation of international humanitarian law.
