Violent anti-immigration protests break out in Belfast after a knife attack in which a man is seriously injured. Multiple outlets report that the incident involves a Sudanese man, described as a refugee or asylum seeker, who is arrested and charged in connection with the attack. News coverage says a widely circulated video of the stabbing spreads online and contributes to unrest.

During the night that follows, masked protesters in parts of east Belfast set vehicles and buildings alight, with fires reported at homes and other properties, including damage to or burning of cars and a bus. Several sources describe protesters blocking roads and attacking police, while emergency services respond to fires and other damage.

Officials and politicians call for calm and condemn the violence, with some commentators characterizing the actions as racially motivated. Reports also note that the suspect is due to appear in court in Northern Ireland on Wednesday. Coverage describes residents being evacuated or forced to flee burning homes in at least one affected street.
