Amnesty International UK have said big tech problems are playing an “active role in fuelling racist violence”.

Responding to the role of social media platforms amid the ongoing racist and Islamophobic violence in the UK, Pat de Brún, Amnesty Deputy Director at Amnesty Tech, said: “Big Tech platforms are offering the far-right a powerful venue to incite hate and organise.

“The racist violence spilling across the streets follows a period of intense scapegoating of refugees and migrants by politicians and others, through dangerous rhetoric and policies. In this context, social media algorithms have actively amplified and escalated xenophobic discourse.

“These toxic algorithms are deliberately designed to prioritise engagement and act as incendiaries that fuel division, disinformation, and hate.”

Violent scenes have erupted in the last week following the killings of three young girls in Southport by 17-year-old Axel Rudakubana. Several others were injured in the attack, with the suspect due to stand trial in January.

Misinformation became rife following the tragic incident, with false reports of Rudakubana’s religion and migration status shared widely on social media. Far-right rioters took to the streets of Southport on the day after the attack, clashing with police and causing severe damage to the town.

A fourth person has pleaded guilty to violent disorder after rioting in Sunderland, police said.

Bradley Makin appeared before magistrates in South Tyneside and pleaded guilty to violent disorder, as well as possession of cocaine and heroin, a Northumbria Police spokesperson said.

The 21-year-old was remanded in custody until his sentencing at Newcastle Crown Court on Friday.

HOPE not hate has responded to a list of locations circulated by the far-right to target tomorrow.

The campaign group said an “anonymous fascist” had shared the “hit list” of targets and called for action “up to and including terrorism”.

The horrifying list includes the addresses of immigration centres, lawyers’ offices and charities.

Joe Mulhall, Director of Research, said: “Understandably, the wide circulation of this list has caused a great deal of distress, unease and fear. Indeed, this list has been compiled precisely to spread these emotions within Muslim and immigrant communities.

“Unfortunately, it is impossible to predict exactly which, if any, of these locations will be targeted by far-right rioters or come under physical attack. Any and all services should be on high alert.”

The Metropolitan Police have vowed to protect London from “one of the worst spates of violent disorder in the last decade”, as more protests are due to take place on Wednesday.

Deputy Assistant Commissioner Andy Valentine, who is in charge of the policing operation, said: “This country is faced with one of the worst spates of violent disorder in the last decade. This is a national critical incident and we will do everything in our power to protect London and its communities.

“We know about the events planned by hateful and divisive groups across the capital tomorrow night. They’ve made their intention to cause disruption and division very clear.

“The scenes of racist, thuggish and criminal behaviour across the country have been deeply shocking. Members of the public and officers have been attacked, many have been injured.

“We will not tolerate this on our streets. We will use every power, tactic and tool available to prevent further scenes of disorder.

“We arrested more than 100 people in central London disorder last week and we will not hesitate to arrest hundreds more if they take to the streets intent on fuelling violence.”

Assistant Chief Constable Paul Court, of Sussex Police, confirmed no criminal violence or disorder had taken place in the county, but warned people against taking part in future unrest.

“I have a clear message to those people considering taking part in this disorder – do not do it –  because we will make you regret your actions,” he said.

“We will use all the powers available to us to hold you to account for your behaviour.

“We have enhanced resources available. Specialist officers on duty and we have many in number, if there are any instances of disorder we will be responding swiftly.

“There is no place in Sussex for racist criminal violent behaviour on our streets and we’re very clear with that message.”

He added that a number of hate crimes had taken place targeting mosques and the Muslim community which are “wholly unacceptable” and “a thorough investigation is taking place into both those incidents”.

Prime Minister Sir Keir Starmer will chair another emergency Cobra meeting on Tuesday evening on continued action to tackle the violent disorder that has been taking place around the country, the PA news agency understands.

Relevant ministers and police chiefs will attend.

“We are willing to look at terrorism offences. I’m aware of at least one instance where that is happening,” Director of Public Prosecutions, Stephen Parkinson, told BBC News.

“Where you have organised groups planning activity for the purposes of advancing [an] ideology… planning really, really serious disruption then yes, we will consider terrorism offences.”

A women’s county cricket match between Essex and Kent has been cancelled tomorrow as fears that further far-right violence could materialise grow.

Essex cricket club said they had had postponed the match “in light of planned protests” ownWednesday following a period of consultation with Essex Police, the ECB and the diverse workforce at Essex Cricket.
