UK Prime Minister Keir Starmer vowed to do "whatever it takes" to bring those responsible to justice. Riots have spread across the country after misinformation was spread about a knife attack that killed three girls.
Police in the northern English city of Rotherham struggled to hold back a group of far-right activists on Sunday, who broke into a hotel believed to be housing asylum seekers.
The disturbance is the latest in a series of violent protests by anti-immigration groups in British towns and cities this week after three girls were killed in a knife attack in Southport in northwest England on Monday.
Footage aired on British TV showed officers with shields targeted by a barrage of projectiles outside the Holiday Inn Express hotel in Rotherham, near Sheffield.
A few minutes later, the protesters can be seen storming the building and removing chairs from inside to use as weapons.
A small fire was also visible while windows in the hotel were smashed.
At least one officer was injured in the confrontation.
