Horn of Africa country (7)
I believe the answer is:
eritrea
'horn of africa country' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for eritrea that I've seen before include "It became independent of Ethiopia in 1993" , "Northeast African country" , "State of northeast Africa" , "part of Africa" , "It declared its independence from Ethiopia in 1993" .)
