Niamey's country (5)
I believe the answer is:
niger
'niamey's country' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for niger that I've seen before include "W. African country" , "Land-locked country and river of W Africa" , "Landlocked W African republic" , "River, Africa's largest delta" , "Country in interior of N Africa, capital Niarney" .)
