London police have arrested four men after a video circulated online showed anti-Semitic abuses were shouted in a street.
The Metropolitan Police said they were arrested on suspicion of racially aggravated public order offences and were taken into custody at a west London police station where they would remain.
The incident occurred as the conflict between Israel and Islamic terrorist group Hamas continued into its eighth day.
The Met traced one of the cars after receiving reports of the incident. A police helicopter was deployed and officers stopped the car at around 6:30 p.m.
Superintendent Jo Edwards, who was in charge of the policing operation, said the men’s behaviour was “utterly shocking and will not be tolerated.”
“I understand that this would have caused considerable concern within the community and we have arranged extra patrols in the St John’s Wood and Golders Green areas this evening,” he said in a statement.
Edwards said another protest in the afternoon “passed peacefully and concluded without any arrests.”
“This, on the streets of London is deeply disturbing. Vile, criminal hatred like this must not be tolerated,” Jenrick wrote.
“Whatever your view of the conflict in Israel and Gaza, there’s no justification for inciting anti-Jewish or Muslim hatred,” Jenrick wrote.
Labour Party leader Sir Keir Starmer also condemned the behaviour.
London Mayor Sadiq Khan thanked the Met for their “swift action” after the four mean were arrested.
“Grateful to our hardworking Met Police officers for their swift action in response to this appalling incident today,” the Muslim Mayor said on Twitter.
“Here in London we have a zero-tolerance approach to hate crime. If you commit a hate crime, you will face arrest,” he added.
In a separate tweet earlier, Khan wrote that “Reports of hateful, intimidating & racist language used on marches & social media this weekend are deeply concerning.”
On Saturday, nine police officers were injured amid efforts to disperse crowds outside the Israeli Embassy in London.
Nine people were arrested on suspicion of violent disorder in London, the Met said.
A further four were arrested on suspicion of breaching health regulations, the force added.
The Met said small pockets of disorder had followed a largely peaceful demonstration.
Demonstrators chanted “free, free Palestine,” and held banners calling for an end to the bombing of Hamas targets in Gaza by Israeli forces.
Former Labour leader Jeremy Corbyn appeared alongside the Palestinian ambassador to the UK at a rally in support of the Palestinians, as the conflict with Israel continues.
The exchange of fire has killed at least 149 people killed in Gaza, including 41 children, and 10 people in Israel, including two children.
