Land also beset by unholy war (6)
I believe the answer is:
rwanda
'land' is the definition.
(Rwanda is an example)
'also beset by unholy war' is the wordplay.
'also' becomes 'and' (I've seen this before).
'beset by' is an insertion indicator ('beset' could historically mean 'cover').
'unholy' indicates an anagram (I've seen this in other clues).
'war' with letters rearranged gives 'rwa'.
'and' put into 'rwa' is 'RWANDA'.
(Other definitions for rwanda that I've seen before include "African republic" , "Language" , "Hutu and Tutsi country" , "Nation" , "Republic in central Africa" .)
