Gasoline bombs were hurled by rioters and set a bus on fire in Belfast, Northern Ireland, Wednesday night, in violence that started last week.

Demonstrators threw the bombs and projectiles across both sides of a concrete “peace wall” separating parts of the community populated by unionist and nationalist supporters, according to police. Many pro-unionists reportedly feel betrayed by the British government amid the post-Brexit world, feeling the effects of new trade arrangements.
