Middle East port (4)
I believe the answer is:
aden
'middle east port' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for aden that I've seen before include "Yemeni gulf" , "somewhere on the Arabian peninsula" , "Dean is out in the Middle Eastern port" , "Dean is in the Yemen, strangely" , "Port city of Yemen" .)
