N Ireland leaders call for calm after night of rioting

LONDON (AP) — Rioters set a hijacked bus on fire and hurled gasoline bombs at police in Belfast in the fourth night of 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, while loyalist and nationalist rioters hurled objects in both directions over the concrete “peace wall” separating Protestant and Catholic areas. U.K. Prime Minister Boris Johnson condemned the unrest, and Northern Ireland’s Belfast-based government was holding an emergency meeting Thursday on the riots. Northern Ireland First Minister Arlene Foster, of the pro-British Democratic Unionist Party, and Deputy First Minister Michelle O’Neill of Irish nationalists Sinn Fein both condemned the disorder and attacks on police.
