City in Yemen (4)
I believe the answer is:
aden
'city in yemen' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for aden that I've seen before include "Former Br. Gulf colony" , "Dane in seaport of Yemen" , "Red Sea port" , "Yemen's chief port" , "Main port of Yemen" .)
