SYDNEY - Australian police fired pepper spray to break up clashes between right-wing nationalists and anti-racism protesters on the streets of Melbourne on Sunday, the latest protest held by anti-immigration groups in the country. Far-right activists from the True Blue Crew, which says it is opposed to refugees and the 'Islamisation' of Australia, faced off with members of a left-wing coalition promoting tolerance in the city. Australia has seen a rise in far-right activist groups and political parties opposed to Islam and Asian immigration following a number of 'lone wolf' attacks by home-grown Islamist radicals. Victoria Police said one person was arrested for possession of a weapon and one detained for breach of the peace, and a knife and a knuckle duster were confiscated. “Police were forced to deploy capsicum spray when a small number of protestors attempted to breach a police line, with one person given aftercare as a result of the capsicum spray,” a spokeswoman said.
