Anger in pubs produces assaults (8)
I believe the answer is:
barrages
'assaults' is the definition.
(barraging is a kind of assaulting)
'anger in pubs' is the wordplay.
'anger' becomes 'rage' (rage is a kind of anger).
'in' is an insertion indicator.
'pubs' becomes 'bars' (I've seen this in other clues).
'rage' put inside 'bars' is 'BARRAGES'.
'produces' acts as a link.
(Other definitions for barrages that I've seen before include "Continuous showers of shell" , "Rapid and continuous deliveries, of gunfire perhaps" , "Bombardments, onslaughts" .)
