Dubai denizens (5)
I believe the answer is:
arabs
'dubai denizens' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for arabs that I've seen before include "Semites" , "eg Saudis" , "Fine horses" , "Graceful horses" , "Semitic people in the Middle East and northern Africa" .)
