A Turkish parliamentary committee has again erupted in chaos over a contentious ruling party proposal to strip legislators of their immunity from prosecution.

Legislators on Monday hurled bottled water at each other across the committee room while others engaged in a fist-fight, forcing the committee head to halt proceedings.

The committee is discussing a proposed constitutional amendment that could pave the way for the trial of several pro-Kurdish legislators on terror-related charges. The proposal was prepared after President Recep Tayyip Erdogan accused the party of being an arm of the outlawed Kurdish rebels.

The move comes amid a surge of violence in Turkey's southeast after a fragile peace process with the rebels collapsed.

A fist-fight also broke out during Thursday's committee meeting and five legislators later sought medical help.
