Saracens (5)
I believe the answer is:
arabs
'saracens' 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 "Semitic people in the Middle East and northern Africa" , "Semitic people of the Middle East and North Africa" , "Graceful horses" , "They live mainly in the Middle East and North Africa" , "Fine horses" .)
