The demonstrators also allegedly threw beer cans and stones at the police.
– What we see is completely unacceptable and will not be tolerated, says a police officer to the newspaper.
Mayor Kim McGuinness says she is “appalled” by the events unfolding.
– If the answer to a tragedy is to use violence and attack the police, it is not protest, it is criminal, she says.
It has also been noisy in Liverpool on Friday. Far-right demonstrators gathered outside a mosque in the city and then clashed with counter-demonstrators.
Riots earlier this week
A wave of similar protests is expected around the UK this weekend, and the police have been adequately staffed to deal with them, writes The Guardian. Earlier this week riots broke out in Southport where police cars were set on fire and stones were thrown at police.
The police suspect that the violence on Tuesday is linked to the far-right group English Defense League, which is said to have spread calls to participate in the protests on social media. The protest in Sunderland is said to have been organized by right-wing extremists, according to The Guardian.
It was on Monday that three girls were killed, and several were seriously injured, after a 17-year-old attacked with a knife in the town of Southport. The children participated in a Taylor Swift-inspired dance class.
