Sanaa, also spelled Sana'a and Sana, is the capital and largest city of Yemen and the capital of the Sanaa Governorate. The city is not part of the Governorate but forms the separate administrative district of ʾAmānat al-ʿĀṣimah. According to the Yemeni constitution, Sanaa is the capital of the country, although the seat of the Yemeni government moved to Aden, the former capital of South Yemen, in the aftermath of the Houthi occupation. Aden was declared as the temporary capital by then-president Abdrabbuh Mansur Hadi in March 2015.
