Sana'a citizen (6)
I believe the answer is:
yemeni
'sana'a citizen' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for yemeni that I've seen before include "ME citizen" , "Someone from Aden?" , "From a country in the Arabian peninsula, capital Sana'a" , "language" , "Native of a country on the Arabian Peninsula" .)
