Pretty self explanatory. Sana'a is the capital of Yemen and was captured by the Houthi movement in 2014.

I will resolve "No" if Sana'a is divided between armies waging a battle or in some kind of ceasefire, but if there's fighting on the city's outskirts/surrounding territory but not its urban core I will resolve "Yes." If they lose it and then take it back during the period I will resolve "Yes," so no matter what don't expect a resolution until the end of the year.
