Brute from Iran? I'm alarmed (6)
I believe the answer is:
animal
'brute' is the definition.
('animal' can be a synonym of 'brute')
'from iran? i'm alarmed' is the wordplay.
'from' indicates a hidden word.
'ANIMAL' can be found hidden inside 'iran im alarmed'.
(Other definitions for animal that I've seen before include "Creature having voluntary movement" , "Kind of instinct" , "Brutish sort" , "Uncivilised person" , "Mammal" .)
