Country by the Red Sea (5)
I believe the answer is:
yemen
'country by the red sea' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for yemen that I've seen before include "Country to south of Saudi Arabia" , "Arab state" , "Arabian republic, capital Sanaa" , "Enemy country in S Arabian peninsula" , "Middle Eastern country" .)
