Here, Belarusians hold revolt (5)
I believe the answer is:
rebel
'revolt' is the definition.
(I've seen this before)
'here belarusians hold' is the wordplay.
'hold' indicates a hidden word (I've seen 'holds' mean this).
'REBEL' is hidden within 'here belarusians'.
(Other definitions for rebel that I've seen before include "One who fights authority" , "One who opposes the powerful" , "Oppose authority" , "Authority fighter" , "Rejector of authority" .)
