War and upset in African country (6)
I believe the answer is:
rwanda
'african country' is the definition.
(Rwanda is an example)
'war and upset' is the wordplay.
'upset' indicates an anagram.
'war'+'and'='warand'
'warand' is an anagram of 'RWANDA'.
'in' acts as a link.
(Other definitions for rwanda that I've seen before include "Scene of a genocide in 1994" , "African republic" , "Central African country" , "Kigali's country" , "Republic in central Africa" .)
