<P> A military intervention was launched by Saudi Arabia in 2015 , leading a coalition of nine African and Middle East countries , to influence the outcome of the Yemeni Civil War in favour of the government of President Abdrabbuh Mansur Hadi . Code - named ' Operation Decisive Storm ( Arabic : عملية عاصفة الحزم ‎ Amaliyyat ' Āṣifat al - Ḥazm ) , the intervention initially consisted of a bombing campaign on Houthi Rebels and later saw a naval blockade and the deployment of ground forces into Yemen . The Saudi - led coalition has attacked the positions of the Houthi militia and loyalists of the former President of Yemen , Ali Abdullah Saleh , allegedly supported by Iran ( See Iran -- Saudi Arabia proxy conflict ) , in response to a request from the internationally - recognized government of President Abdrabbuh Mansur Hadi . The perception that Iran is directly controlling the Houthis is contradicted due to statement made on April 2015 , by National Security Council spokeswoman Bernadette Meehan : `` It remains our assessment that Iran does not exert command and control over the Houthis in Yemen '' </P>
