what is the reason of war between saudi and yemen
Saudi Arabian-led intervention in Yemen 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.[111][58][112][113] 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.[114][115] 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"[116][117]
