Suella Braverman has condemned what she described as "sick, inflammatory and, in some cases, clearly criminal chants, placards and paraphernalia openly on display at the march" on Saturday.
In her first comments since Armistice Day saw an estimated 300,000 descend on the capital to march for a ceasefire in Gaza, the Home Secretary spoke out against violence and aggression" from protesters and counter-protesters and thanked the police.
Writing on social media site X on Sunday, she said: “Our brave police officers deserve the thanks of every decent citizen for their professionalism in the face of violence and aggression from protesters and counter-protesters in London yesterday.
“That multiple officers were injured doing their duty is an outrage.”
She said “further action” is needed to tackle antisemitism as she zeroed in on placards and chants by some pro-Palestinian protesters.
“The sick, inflammatory and, in some cases, clearly criminal chants, placards and paraphernalia openly on display at the march mark a new low. Antisemitism and other forms of racism together with the valorising of terrorism on such a scale is deeply troubling.
“This can’t go on. Week by week, the streets of London are being polluted by hate, violence, and antisemitism. Members of the public are being mobbed and intimidated. Jewish people in particular feel threatened. Further action is necessary.”
The Metropolitan Police said seven men have been charged with a variety of offences including assault on an emergency worker, criminal damage and possession of an offensive weapon.
Officers made 145 arrests during the pro-Palestinian demonstration and counter-protest by far-right groups, the force said. The majority of these arrests were made up of counter-protesters.
Mrs Braverman has been under fire for inflaming tensions after she branded pro-Palestinian protesters “hate marchers” and accused the police of bias for letting the rally coinciding with remembrance events go ahead.
Prime Minister Rishi Sunak is facing intensifying calls to sack her.
