Middle Eastern port (4)
I believe the answer is:
aden
'middle eastern port' 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 "Commercial capital of Yemen" , "Yemeni gulf" , "Dane in seaport of Yemen" , "Yemen's chief port" , "Strange Dane to be in the Yemen" .)
