Pro-Palestine protesters have clashed with police during a planned community picket outside a metal processing facility in Melbourne.
About 60 people gathered outside the Electromold Australia factory in Thomastown about 4.30am.
It was the fourth time demonstrators have targeted the factory.
The demonstrators attempted to disrupt the supply chain of F35 fighter jets, which they said are flown by Israel over Gaza.
Tensions boiled over when police asked the crowd to move on, with officers deploying pepper spray.
Police arrested three men and three women at the scene.
They have all since been released and are expected to be charged on summons with besetting premises, resist and hinder police.
Police are investigating the criminal damage to the front gate of the factory.
