What to know after anti-immigrant violence flares in a Northern Ireland town

Anti-immigrant violence in Ballymena, Northern Ireland, injured 17 police officers after a second night of rioting. The unrest followed a march supporting a sexual assault victim, with two boys charged. Rioters threw projectiles, set fires, and targeted homes. Police responded with water cannons and rubber bullets, arresting five. Authorities blame social media agitators and unchecked migration for fueling "racist thuggery."
