Five Turkish legislators have been hurt in a brawl that broke out in parliament during which chairs were allegedly hurled and politicians attacked with the speaker's gavel and bell, reports say.

The state-run Anadolu Agency said the fighting erupted as opposition legislators attempted to delay the start of a debate on a contentious security bill that would give police greater search and arrest powers.

The fighting took place during a closed-door session at the parliament in Ankara after opposition parties submitted several unrelated motions in their bid to obstruct the bill.

Ertugrul Kurkcu of the pro-Kurdish party said stenographers' chairs were thrown and two legislators were hit with the gavel and bell.

Two of the legislators were treated in hospital and Mr Kurkcu and two others were treated at the parliament's infirmary.
