Eight people were arrested after pro-transgender demonstrators clashed with Christian protesters.

Christian activists with Mayday USA organised a demonstration outside Seattle City Hall on Tuesday that descended into aggressive scenes after it was swarmed by pro-transgender counter-protesters.

Footage of the incident shows a woman and three children surrounded by counter-protesters who heckled and pointed at her.

The woman, dressed in a blue vest and a hat, is holding a baby in her arms and appears to be with her partner who is holding the hands of two children, one of whom is crying.

As police officers rush in to diffuse the situation, demonstrators can be heard shouting “get the kids out of here” and accuse the woman of “instigating” the situation.
