Disorder and chaos spread across U.K. towns and cities through Sunday, with police arresting at least 100 after far-right protests became violent.

Demonstrators in Rotherham, northern England, attacked police and targeted hotels on Sunday, according to the Press Association. Videos on social media appeared to show demonstrators storming into a Holiday Express Inn and starting a fire. Such properties are targeted by rioters who believe asylum seekers are housed in them.

Disturbances broke out in towns and cities across the country on Saturday, including Blackpool and Bristol, with a number of police officers attacked and injured. The riots represent one of the biggest challenges facing the month-old Labour government, as it struggles to rein in the unrest.

Tensions have been rising since an attack on a Taylor Swift-themed dance party left three young girls dead in Southport, near Liverpool, on Monday. The attacker was named as Axel Rudakubana, a 17-year-old from a village near Southport who was born in Cardiff.

Fueled by an online misinformation campaign, the attack was seized upon by far-right protesters, some of whom took to the street chanting anti-immigration slogans this weekend.

Home Secretary Yvette Cooper pledged the government’s “full backing” for the police in dealing with the unrest. “Anyone who gets involved in criminal disorder and violent thuggery on our streets will have to pay the price,” she said in a video posted to X.

Around 300 people were involved in disturbances in the Walton area of Liverpool on Saturday night, according to Merseyside Police. The force, also responsible for Southport, said that a local convenience store was set on fire and that a library was damaged, while firefighters who attended to the scene had a missile thrown at their vehicle. The police force said it made 23 arrests on Saturday.

“We will do whatever it takes to make sure that people can get through the court system,” Diana Johnson, the policing minister, said in an interview on Sky News Sunday. Courts could sit through the night to deal with the large number of people arrested if necessary, she added.

After the Southport attack, a number of influential right-wing accounts on X spread false information about Rudakubana, including claims that he was an asylum seeker or a refugee. That led to protests and skirmishes with police, including in London, earlier in the week.

In Hull, as demonstrators gathered outside a hotel that houses asylum seekers, a number of windows were smashed and bottles thrown. In videos uploaded to social media many of the protesters can be heard chanting “stop the boats,” a reference to crossings made from the European continent by migrants attempting to get to Britain.

Three police officers were hospitalized after violence in Sunderland, the police force there said in a statement. There were also disturbances in Leicester, Stoke-on Trent, Nottingham and Manchester.
