Amnesty International says it is “deeply concerning” that police made 474 arrests during a Palestine Action demonstration in London.
Metropolitan Police said 466 were detained under the Terrorism Act for showing support for a banned group.
Eight more people were arrested for other offences, including five for assaulting officers.
The Met said it was the most arrests it’s made related to a single operation in at least the past decade.

Organiser of the event, Defend Our Juries, earlier said up to 700 people were at the event in Parliament Square and claimed police were preparing for the “largest mass arrest in their history”.
The group said those arrested included former Guantanamo Bay detainee Moazzam Begg, NHS workers, quakers and a blind wheelchair user.
Amnesty International UK’s chief executive Sacha Deshmukh said in a statement: “The protesters in Parliament Square were not inciting violence and it is entirely disproportionate to the point of absurdity to be treating them as terrorists.
“Instead of criminalising peaceful demonstrators, the government should be focusing on taking immediate and unequivocal action to put a stop to Israel’s genocide and ending any risk of UK complicity in it.”
The Met said a “significant number of people” at the event were seen “displaying placards expressing support for Palestine Action”.
Home Secretary Yvette Cooper said: “The right to protest is one we protect fiercely but this is very different from displaying support for this one specific and narrow, proscribed organisation.
“Palestine Action was proscribed based on strong security advice following serious attacks the group has committed, involving violence, significant injuries and extensive criminal damage.”

Palestine Action supporters arrested at protest
Police said those arrested had been taken to processing points in Westminster and any whose details could be confirmed were bailed on condition they didn’t attend further Palestine Action support events.
Others whose details could not be verified, possibly because they refused to give them, were taken to custody suites across London.

The protests have put a strain on authorities’ capacity to cope.
Sky News understands senior leaders in the prison service, known as “Capacity Gold”, met today to discuss how to deal with the large number of arrests as the male prison estate is close to full.
It’s understood 800 inmates were moved out of the busiest jails in and around London beforehand.
In a statement, the Metropolitan Police Federation said: “Thinking of our colleagues and wishing all assaulted officers well. Remember there are no ‘extra’ police officers – just the same ones having their days off cancelled, having to work longer shifts and being moved from other areas. Officers are emotionally and physically exhausted.”
‘We felt compelled to speak out’
The first of the arrests began just before 1pm, when a man waving a placard that read “I support Palestine Action” was stopped by police, writes Gurpreet Narwan, reporting from Parliament Square.
Officers told him he was showing support for a terrorist organisation, searched him and ushered him away.
The action soon escalated. Among the people arrested today were a number of elderly people, a blind man in a wheelchair, and a teenager.
They were protesting peacefully, with a number of people pointedly seating themselves below statues of Mahatma Gandhi and the suffragette Millicent Fawcett.
They told Sky News that they were fully expecting to be arrested but that they felt compelled to speak out and defend the right to protest.
One protester said: “I don’t think I’m a criminal. That’s not the person I am.”
However, he said he was being guided by his faith and his conscience.
Things calmed down after a few hours but there was a heavy police presence well into the afternoon and early evening.
Legislation to ban Palestine Action came into force on 5 July, making it a criminal offence to show support for the organisation, carrying a prison sentence of up to 14 years.
Defend Our Juries said earlier this week the protest would still go ahead, following several similar demonstrations since it was outlawed last month.
On Saturday, a spokesperson said: “Palestine Action and people holding cardboard signs present no danger to the public at large.”

Human rights advocates Amnesty International described the arrests of so many people under UK terrorism law as “deeply concerning”.
Another march organised by the Palestine Coalition, which is a separate group, set off from Russell Square and assembled on Whitehall.
The Met Police said one person had been arrested there for showing a placard in support of Palestine Action.

Earlier this week, three people charged as a result of illegal Palestine Action activity were named.
Jeremy Shippam, 71, of West Sussex, Judit Murray, also 71, of Surrey, and Fiona Maclean, 53, of Hackney in east London, will appear at Westminster Magistrates’ Court on 16 September.
The ban on Palestine Action faces a legal challenge in November after the High Court granted a full judicial review to Palestine Action co-founder Huda Ammori.
Marnie’s first serious relationship came when she was 16-years-old.
Warning: This article contains references to strangulation, coercive control and domestic abuse.
She was naturally excited when a former friend became her first boyfriend.
But after a whirlwind few months, everything changed with a slow, determined peeling away of her personality.
“There was isolation, then it was the phone checking,” says Marnie.
As a survivor of abuse, we are not using her real name.
“When I would go out with my friends or do something, I’d get constant phone calls and messages,” she says.
“I wouldn’t be left alone to sort of enjoy my time with my friends. Sometimes he might turn up there, because I just wasn’t trusted to just go and even do something minor like get my nails done.”

He eventually stopped her from seeing friends, shouted at her unnecessarily, and accused her of looking at other men when they would go out.
If she ever had any alone time, he would bombard her with calls and texts; she wasn’t allowed to do anything without him knowing where she was.
He monitored her phone constantly.
“Sometimes I didn’t even know someone had messaged me.
“My mum maybe messaged to ask me where I was. He would delete the message and put my phone away, so then I wouldn’t even have a clue my mum had tried to reach me.”
The toll of what Marnie experienced was only realised 10 years later when she sought help for frequent panic attacks.
She struggled to comprehend the damage her abuser had inflicted when she was diagnosed with PTSD.
This is what psychological abuse and coercive control looks like.

‘His hands were on my throat – he didn’t stop’
Young women and girls in the UK are increasingly falling victim, with incidents of domestic abuse spiralling among under-25s.
Exclusive data shared with Sky News, gathered by domestic abuse charity Refuge, reveals a disturbing rise in incidents between April 2024 and March 2025.
Psychological abuse was the most commonly reported form of harm, affecting 73% of young women and girls.
Of those experiencing this form of manipulation, 49% said their perpetrator had threatened to harm them and a further 35% said their abuser had threatened to kill them.
Among the 62% of 16-25 year olds surveyed who had reported suffering from physical violence, half of them said they had been strangled or suffocated.
Earlier this year, Sky News reported that school children were asking for advice on strangulation, but Kate Lexen, director of services at charity Tender, says children as young as nine are asking about violent pornography and displaying misogynistic behaviour.

“What we’re doing is preventing what those misogynistic behaviours can then escalate onto,” Ms Lexen says.
Tender has been running workshops and lessons on healthy relationships in primary and secondary schools and colleges for over 20 years.
Children as young as nine ‘talking about strangulation’
Speaking to Sky News, Ms Lexen says new topics are being brought up in sessions, which practitioners and teachers are adapting to.
“We’re finding those Year 5 and Year 6 students, so ages 9, 10 and 11, are talking about strangulation, they’re talking about attitudes that they’ve read online and starting to bring in some of those attitudes from some of those misogynistic influencers.
“There are ways that they’re talking about and to their female teachers.
“We’re finding that from talking to teachers as well that they are really struggling to work out how to broach these topics with the students that they are working with and how to make that a really safe space and open space to have those conversations in an age-appropriate way, which can be very challenging.”

Hidden domestic abuse deaths
Charities like Tender exist to prevent domestic abuse and sexual violence.
Ms Lexen says without tackling misogynistic behaviours “early on with effective prevention education” then the repercussions, as the data for under 25s proves, will be “astronomical”.
At Refuge, it is already evident. Elaha Walizadeh, senior programme manager for children and young people, says the charity has seen a rise in referrals since last year.

“We have also seen the dynamics of abuse changing,” she adds. “So with psychological abuse being reported, we’ve seen a rise in that and non-fatal strangulation cases, we’ve seen a rise in as well.
“Our frontline workers are telling us that the young people are telling them usually abuse starts from smaller signs. So things like coercive control, where the perpetrators are stopping them from seeing friends and family. It then builds.”
Misogyny to violent behaviour might seem like a leap.
But experts and survivors are testament to the fact that it is happening.
It says human rights in the UK “worsened” in 2024, with “credible reports of serious restrictions on freedom of expression”, as well as “crimes, violence, or threats of violence motivated by antisemitism” since the 7 October Hamas attack against Israel.
On free speech, while “generally provided” for, the report cites “specific areas of concern” around limits on “political speech deemed ‘hateful’ or ‘offensive'”.
Sir Keir Starmer has previously defended the UK’s record on free speech after concerns were raised by Mr Vance.
In response to the report, a UK government spokesperson said: “Free speech is vital for democracy around the world including here in the UK, and we are proud to uphold freedoms whilst keeping our citizens safe.”

The US report highlights Britain’s public space protection orders, which allow councils to restrict certain activities in some public places to prevent antisocial behaviour.
It also references “safe access zones” around abortion clinics, which the Home Office says are designed to protect women from harassment or distress.
They have been criticised by Mr Vance before, notably back in February during a headline-grabbing speech at the Munich Security Conference.
Ministers have said the Online Safety Act is about protecting children, and repeatedly gone so far as to suggest people who are opposed to it are on the side of predators.

Why do people want to repeal the Online Safety Act?
The report comes months after Sir Keir bit back at Mr Vance during a summit at the White House, cutting in when Donald Trump’s VP claimed there are “infringements on free speech” in the UK.
“We’ve had free speech for a very long time, it will last a long time, and we are very proud of that,” the PM said.
But Mr Vance again raised concerns during a meeting with Foreign Secretary David Lammy at his country estate in Kent last week, saying he didn’t want the UK to go down a “very dark path” of losing free speech.

The Trump administration itself has been accused of trying to curtail free speech and stifle criticism, most notably by targeting universities – Harvard chief among them.
