Houthi-controlled territory of Yemen

Houthi Yemen constitutes the areas of Yemen under the de facto governance of the Houthis, a Zaydi Shia revivalist political and military organization. Since their takeover in September 2014, the Houthis have maintained control over significant portions of northern and western Yemen, including the capital, Sanaa. Their administration, the Supreme Political Council, operates in opposition to the internationally recognized government of Yemen. The Houthis aim to govern all of Yemen and support external movements against the United States, Israel, and Saudi Arabia. Because of the Houthis' ideological background, the conflict in Yemen is widely seen as a front of the Iran–Saudi Arabia proxy war.

In September 2014, during the Yemeni civil war, Houthi insurgents ousted president Abdrabbuh Mansur Hadi from the capital, Sanaa. A Saudi Arabian-led military intervention in 2015 aimed at restoring Hadi's government, but several proto-state entities claim to govern Yemen. At least 56,000 civilians and combatants have been killed in armed violence amid the Yemeni civil war since January 2016. The war has resulted in a famine affecting 17 million people. The lack of safe drinking water, caused by depleted aquifers and the destruction of the country's water infrastructure, has also caused the largest, fastest-spreading cholera outbreak in modern history, with the number of suspected cases exceeding 994,751. Over 2,226 people have died since the outbreak began to spread rapidly at the end of April 2017. The ongoing humanitarian crisis and conflict has received widespread criticism for having a dramatic worsening effect on Yemen's humanitarian situation.
