Turkish politicians have scuffled for a second day in parliament over a new security bill which critics say aims to crush dissent. Ruling and opposition parties' MPs traded punches and pushed each other, and one opposition MP fell down a set of stairs. Earlier in the week, five MPs were injured in a similar fight that saw chairs fly.
In this gallery, we look at parliamentary punch-ups around the world (but mostly Turkey, Ukraine and Taiwan) in recent years.
