Rwandan expresses disapproval over India (5)
I believe the answer is:
tutsi
'rwandan' is the definition.
(Tutsis are an African ethnic group)
'expresses disapproval over india' is the wordplay.
'expresses disapproval' becomes 'tuts' (tutting is a disapproving sound).
'over' is a charade indicator (letters next to each other) (in a down clue, some letters go over others).
'india' becomes 'i' (phonetic alphabet: alpha, bravo, charlie etc.).
'tuts'+'i'='TUTSI'
(Other definitions for tutsi that I've seen before include "tribesman" , "Rwanda tribe member" , "Rwandan group" , "African tribe" , "Person from Burundi" .)
