Far-right activists and anti-racism groups faced off in cities across the U.K. on Saturday as tensions remained high following a stabbing rampage at a dance class earlier this week that left three girls dead and several wounded.

With dozens of protests scheduled to take place around the country, police have mounted a significant security operation, deploying thousands more officers onto the streets, many in their riot gear. Police have also made more prison cells available and are using surveillance and facial recognition technology.

On Saturday, there were some isolated incidents of violence despite the high police presence. Bricks were thrown at police officers in Stoke-on-Trent in central England while the windows of a hotel used to house migrants were smashed in the northeast city of Hull. And in Liverpool, a police officer on a motorbike was kicked and knocked off his vehicle.

Scuffles have also been reported in Belfast, Manchester and Nottingham. In London, thousands of pro-Palestinian marched to protest against Israel91裸聊视频檚 military operation in Gaza.

The latest standoffs come a day after protesters in Sunderland in northeast England tossed beer barrels and rocks at police officers. A car and the building next door to a police station were set ablaze.

The violence in Sunderland, which saw ten people arrested, is the latest over the past few days and nights, which have ostensibly erupted in the wake of Monday91裸聊视频檚 stabbing attack in the northwest seaside town of Southport. A 17-year-old male has been arrested.

False rumors spread online about the young man91裸聊视频檚 identity, being a Muslim and an immigrant, fueled anger among far-right supporters. Suspects under 18 are usually not named in the U.K., but Judge Andrew Menary ordered Axel Rudakubana, born in Wales to Rwandan parents, to be identified, in part to stop the spread of misinformation.

In a press briefing on Saturday after the clear-up, Northumbria Police Chief Superintendent Mark Hall described the violent protests in Sunderland as 91裸聊视频渦nforgivable91裸聊视频� and that four police officers were injured, three as a direct result of the disorder. He also said a mounted rider sustained serious injuries in an accident and is receiving treatment in hospital.

91裸聊视频淒uring the course of the evening, our officers were met with serious and sustained levels of violence,91裸聊视频� he said. 91裸聊视频淢ake no mistake, if you were involved last night, expect to be met with the full force of the law.91裸聊视频�

Police said many of the protests are being organized online by shadowy far-right groups, who are mobilizing support online with phrases like 91裸聊视频渆nough is enough,91裸聊视频� 91裸聊视频渟ave our kids91裸聊视频� and 91裸聊视频渟top the boats.91裸聊视频� Counter-protests are also anticipated with the organization Stand Up To Racism rallying against Islamophobia and the far-right.

Britain91裸聊视频檚 new Labour Home Secretary Yvette Cooper said on social media platform X Saturday that criminals attacking the police and stoking disorder will 91裸聊视频減ay the price91裸聊视频� for their thuggery and that the police have the full backing of the government to 91裸聊视频渢ake the strongest possible action.91裸聊视频�

Far-right demonstrators have held several violent protests since the stabbing attack, clashing with police Tuesday outside a mosque in Southport 91裸聊视频� near the scene of the horrific stabbing 91裸聊视频� and hurling beer cans, bottles and flares near the prime minister91裸聊视频檚 office in London the next day. Many in Southport have expressed their anger at the organized acts of violence in the wake of the tragedy.

The attack Monday on children at a Taylor Swift-themed summer dance class shocked a country where knife crime is a long-standing and vexing problem, though mass stabbings are rare.

Rudakubana, has been charged with murder over the attack that killed Alice Dasilva Aguiar, 9, Elsie Dot Stancombe, 7, and Bebe King, 6. He also has been charged with 10 counts of attempted murder for the eight children and two adults who were wounded.

Prime Minister Keir Starmer has blamed the violence on 91裸聊视频渇ar-right hatred91裸聊视频� and vowed to end the mayhem. He said police across the U.K. would be given more resources to stop 91裸聊视频渁 breakdown in law and order on our streets.91裸聊视频�

At a news conference Thursday, the prime minister said the street violence was 91裸聊视频渃learly driven by far-right hatred91裸聊视频� as he announced a program enabling police to better share intelligence across agencies and move quickly to make arrests.

91裸聊视频淭his is coordinated; this is deliberate,91裸聊视频� Starmer said. 91裸聊视频淭his is not a protest that has got out of hand. It is a group of individuals who are absolutely bent on violence.91裸聊视频�
