The Arab leaders have reaffirmed full support to the "Determination Storm" operation in support of legitimacy in Yemen. They empathized that the operation was based on the Arab Treaty of Joint Defense, the Arab League Charter and Article 51 of the UN Charter, as well as the responsibilities of maintaining the national unity, sovereignty and independence of the Arab states. The Arab leaders expressed hope that the compelling military measures would restore security and stability to all Yemen under constitutional legitimacy, countering Houthis' attempts supported by external parties. These external parties aim to threaten security of Yemen, the region and the Arab national security, as well as the international peace and security through sequestration of the Yemeni will, arousing seditions and dismantling the country's social fabric and national unity. The Arab leaders urged the Houthi militias to immediately withdraw from the capital Sana'a, other towns, and the government institutions as well as normalizing the security situation in Sana'a and other governorates, besides returning the heavy and medium weaponry to the constitutional legitimate authorities. The Arab leaders reiterated the full commitment to Yemen's unity, and respect of its sovereignty and independence, rejecting all forms of intervention in its internal affairs. They voiced support to the Yemeni people and their expectations for freedom, democracy and social justice, as well as enabling them to achieve comprehensive development. --More 18:00 LOCAL TIME 15:00 GMT www.spa.gov.sa/w
