In 2014–2015, Houthis took over the government in Sanaa with the help of the former president Ali Abdullah Saleh, and announced the fall of the current government of Abdrabbuh Mansur Hadi. Houthis have gained control of most of the northern part of Yemen's territory and since 2015 have been resisting the Saudi-led military intervention in Yemen that claims to seek to restore the internationally recognized Yemeni government to power. Additionally, the Islamic State militant group has attacked all of the conflict's major parties including Houthis, Saleh forces, the Yemeni government, and the Saudi Arabian-led coalition forces. The Houthis have launched repeated missile and drone attacks against Saudi cities, widely seen as a proxy war between Saudi Arabia and Iran.
