The New South Wales premier, Chris Minns, has vowed to stop further pro-Palestinian marches in Sydney after apologising for allowing Monday night’s event that ended with antisemitic slurs being hurled on the steps of the Sydney Opera House.

At the time, the globally recognised Sydney venue had been lit up blue and white in support of Israel, and the protesters had been allowed to march from Town Hall to the steps by police, before the chanting and flare-throwing began.
