Saudi Arabian–led intervention in Yemen

On 26 March 2015, Saudi Arabia, leading a coalition of nine countries from West Asia and North Africa, launched an intervention in the Yemeni Civil War in response to calls from the president of Yemen Abdrabbuh Mansur Hadi for military support after he was ousted by the Houthi movement. The conflict ignited between the government forces, the Houthi rebels and other armed groups after the draft constitution and power-sharing arrangements collapsed, despite progress in the political transition led by the United Nations at that time, leading to an escalation of violence in mid-2014. The Houthis and allied units of the armed forces seized control of Sana’a and other parts of the country in September 2014 and in the following months. This prompted President Hadi to ask Saudi Arabia to intervene against the Iranian-backed Houthis.

Code-named Operation Decisive Storm (Arabic: عملية عاصفة الحزم, romanized: Amaliyyat 'Āṣifat al-Ḥazm), the intervention initially consisted of a bombing campaign on Houthi rebels and later a naval blockade and the deployment of ground forces into Yemen.[74] The Saudi-led coalition has attacked the positions of the Houthi militia and loyalists of the former President of Yemen, Ali Abdullah Saleh, who are supported by Iran (see Iran–Saudi Arabia proxy conflict).

Fighter jets and ground forces from Egypt, Morocco, Jordan, Sudan, the United Arab Emirates, Kuwait, Qatar, Bahrain, and Academi (formerly called Blackwater) took part in the operation. Djibouti, Eritrea, and Somalia made their airspace, territorial waters, and military bases available to the coalition.[75]

The United States provided intelligence and logistical support, including aerial refueling and search-and-rescue for downed coalition pilots.[13][76] It also accelerated the sale of weapons to coalition states[77] and continued strikes against AQAP. In January 2016, the Saudi foreign minister said that US and British military officials were in the command and control centre responsible for Saudi-led air strikes in Yemen, having access to lists of targets but were not involved in choosing targets.[78][79][80]

The war received widespread criticism and had a dramatic worsening effect on Yemen's humanitarian situation, that reached the level of a "humanitarian disaster"[23] or "humanitarian catastrophe".[81] The question of whether or not the intervention is in compliance with Article 2(4) of the UN Charter has been the matter of academic dispute.[82][83][84]

The conflict's status was described a "military stalemate" in 2019.[85] The global COVID-19 pandemic is said to have given Saudi Arabia an opportunity to review its interests in Yemen.[86] In early 2020, it was said that Saudi Arabia was searching for an exit strategy, amid the COVID-19 pandemic and military defeats.[87]

On 29 March 2022, the Saudi-led coalition announced that it would cease all hostilities within Yemen starting at 6 A.M. the following day, in order to facilitate political talks and peacekeeping efforts.[88]
