In the wake of a series of anti-Semitic attacks in London over the weekend, the city’s Mayor, Sadiq Khan, sought to reassure the Jewish community about its safety.

The incidents included a brick with images of swastikas and anti-Semitic messages thrown through the window of a Jewish home in the Edgware neighborhood on Saturday morning. Hours earlier in the same neighborhood, a group of identifiably Jewish people were pelted with eggs while walking home from Shabbat dinner.

Also, swastikas were discovered drawn on a property in the borough of Barnet, a city-owned garbage bin was defaced with anti-Jewish invective and a poster for the film “Denial” was vandalized with graffiti. The film deals with Holocaust denier David Irving’s legal case against scholar Deborah Lipstadt, who won her case.

According to the Shomrim volunteer security group, the atacks were intended to “instil fear” in the Jewish community.

“The best response to these disgusting acts is to ensure that the perpetrators are caught. We are working closely with the Metropolitan Police Service and appeal for any witnesses to contact police or Shomrim.”

The London Metropolitan Police reportedly is investigating the incidents as hate crimes.

“Anti-Semitic crime is on the rise and these cowardly attacks must lead to arrests and convictions,” said. Stephen Silverman from the Campaign Against Anti-Semitism. “Jewish families in our capital should not be living in fear of anti-Semitic attacks,” he added.

A spokesperson for the Board of Deputies of British Jews said: “The low-lives who think it big or clever to menace Jewish families over the weekend deserve nothing short of our contempt. The perpetrators should face the full force of law.’’

According to a report delivered by the Israeli Diaspora Affairs on anti-Semitism worldwide, the United Kingdom experienced a rise in anti-Semitic incidents in 2016, including a 62% rise in the number of violent attacks in London alone

While the report noted that the majority of the incidents in Britain were perpetrated by far-right actors, the left-leaning Labour Party was also singled out for scrutiny, which saw over 50 members suspended in 2016 for anti-Semitic comments they made, most notably former London mayor Ken Livingstone’s remarks that “before he went mad and ended up killing six million Jews,” Nazi leader Adolf Hitler had been “supporting Zionism.”

In an interview with Jewish News at the annual Holocaust Memorial Day commemoration in City Hall, London’s Mayor Sadiq Khan declared: “No incident is too trivial. I want London’s Jewish community to feel confident to report every incident to the police. There is nothing trivial about having a brick hurled through your window or an egg thrown at you.”

He added: “Police are studying CCTV footage from these incidents and patrols in north London, particularly Barnet, will reassure the Jewish community that we’re on their side. We are here for them. It’s not simply the victim who is affected. The ripples of trauma are felt by the entire Jewish community. We’ve got to understand that psychological impact.”

Speaking of the importance of Holocaust Memorial Day, the mayor referred to his visit to Auschwitz-Birkenau as “an experience I’ll never forget”, calling it “distressing haunting and moving”.

Khan said it’s crucial we have a “zero-tolerance attitude towards hate crime”, because not addressing small incidents can lead things like the Holocaust”.

Turning to the turbulent relations between his (Labour) party and the Jewish community, Khan said there is “no place in the Labour Party for racism”, adding: “If there are concerns about anti-Semitism in the party they should be taken seriously.”
