Members of Turkey's ruling AK Party and the pro-Kurdish opposition have traded kicks and punches, and thrown water at each other in Parliament, halting talks about lifting parliamentarians' immunity from prosecution.
The law, championed by the ruling AKP, would strip members of Parliament of their legal immunity.
The Kurdish-rooted Peoples' Democratic Party (HDP) says the bill is targeting them and is aimed at suppressing dissent.
President Tayyip Erdogan, who founded the AKP, has called for members of HDP to face prosecution, accusing them of being an extension of the outlawed militant group, the Kurdistan Workers Party (PKK).
Scores of deputies crammed into a committee room to debate the bill, according to a Reuters reporter in Parliament.
