Anti-abortion and pro-choice protestors clash in Melbourne

Anti-abortion protestors have clashed with pro-choice campaigners in Melbourne during another day of demonstrations.

CBD traffic was gridlocked, and extra police were on patrol trying to keep the peace as tensions flared between the groups.

A loud and publish stoush erupted between opposing protestors while a heavy police presence kept the crowds under control.

Main roads in the CBD were closed which stalled traffic.

Outside Parliament one man was led away for an unknown offence, as opposing groups traded barbs and tried to drown each other out.

Led by conservative Liberal MP Bernie Finn, anti-abortion groups want to change laws brought in eleven years ago that allow pregnancy terminations.
