Fury in Liberian uprising (3)
I believe the answer is:
ire
'fury' is the definition.
(ire is intense rage)
'in liberian uprising' is the wordplay.
'in' says the answer is hidden in the clue.
'uprising' is a reversal indicator.
'eri' is hidden in the letters of 'liberian'.
'eri' written backwards gives 'IRE'.
(Other definitions for ire that I've seen before include "Anger among admirers" , "Choler" , "heat" , "passion" , "Anger, annoyance" .)
