@guardian: Protests against immigration have erupted into violence in Northern Ireland after far-right activists called for demonstrations in response to a knife attack that was captured in a graphic video. Crowds that included masked men burned vehicles and houses and blocked roads in and around Belfast on Tuesday night, hours after figures including Elon Musk and Tommy Robinson encouraged people to take to the streets. Protesters hijacked and burned a bus in the east of the city and set fire to cars, from which smoke poured while sirens sounded and a police helicopter hovered above. The unrest flared hours after police charged a 30-year-old asylum seeker from Sudan with attempted murder in connection with an attack in north Belfast on Monday night that left a man critically injured and prompted widespread shock and condemnation. The suspect is to appear at Belfast magistrates court today – tap link in bio to follow the latest news on the live blog. #TheGuardian #GuardianNews #Belfast
