15 May, 2011
Police have been forced to intervene during a clash between the gay and lesbian community and a group of street preachers in Adelaide.
The violence broke out during a rally to mark International Day Against Homophobia and Transphobia on Saturday.
The protest began peacefully with 150 members of the gay and lesbian community gathering to stage a mass wedding, calling for equal rights for gay marriage.
But when members of the Christian Street Church crashed the rally, tension escalated.
