The leader of the Proud Boys extremist group has been sentenced to more than five months in jail for burning a Black Lives Matter banner that was torn down from a historic church in Washington DC.

The Canadian government has designated the Proud Boys group as a terrorist entity, noting they played a pivotal role in the insurrection at the US Capitol on January 6.

A judge has banned the leader of the Proud Boys from the US capital after he was accused of vandalising a Black Lives Matter banner at a historic black church and found with high-capacity firearm magazines when he was arrested.
