The United Nations has expressed concern over the attack on Abha International Airport by a hostile Houthi projectile, urging all parties to prevent such incidents which escalate the current situation, pose a serious threat to national and regional security, and undermine the political process in Yemen led by the UN. UN Spokesman Farhan Haq said at the daily press conference that the UN reiterates the Security Council's latest statement which called on all parties to ensure the protection of civilians and vital civilian infrastructure in accordance with international humanitarian law.
