Post-Brexit violence rocks Belfast for another night, threatening region's uneasy political balance

Belfast, Northern Ireland — Rioters set a hijacked bus on fire and hurled gasoline bombs at police in Belfast in at least the fourth night of serious violence in a week in Northern Ireland, where Brexit has unsettled an uneasy political balance.

Youths threw projectiles and petrol bombs at police on Wednesday night in the Protestant Shankill Road area, while rioters lobbed bricks, fireworks and petrol bombs in both directions over the concrete "peace wall" separating the Shankill Road from a neighboring Irish nationalist area. Police Service of Northern Ireland Assistant Chief Constable Jonathan Roberts said several hundred people gathered on both sides of a gate in the wall, where "crowds ... were committing serious criminal offenses, both attacking police and attacking each other."
