In the early hours of April 18, 2026, the Kenton United Synagogue in Harrow, northwest London, became the latest target in a disturbing pattern of arson attacks against Jewish sites across the city. The incident, which caused minor smoke damage to a medical room but thankfully resulted in no injuries, is being investigated by counter-terrorism police as part of a broader probe into what appears to be a concerted campaign of intimidation against the Jewish community.
According to The Independent, officers on deterrence and reassurance patrols spotted damage to a window at the synagogue around midnight. Upon closer inspection, they discovered smoke inside and evidence that a bottle containing an accelerant had been thrown through the window. The London Fire Brigade responded swiftly, confirming there was no further fire risk. The building, a place of worship and community, was closed following the attack. Rabbi Yehuda Black expressed his dismay, saying, "I was very upset to hear about what happened. Our synagogue is a beautiful synagogue. It's so unfortunate that it has been damaged in such a way." He added that there were hopes the synagogue would reopen in a few days, a testament to the community's resilience.
This latest attack follows a string of similar incidents in recent weeks. On April 17, a building formerly used by a Jewish charity in Hendon was targeted by a man who lit a plastic bag at the entrance before fleeing. Just days earlier, bottles—one thought to contain petrol—were placed near Finchley Reform Synagogue, though they were not ignited. Last month, four ambulances run by a Jewish charity were torched in Golders Green, resulting in several arrests. These attacks, while causing relatively minor physical damage, have sent shockwaves through the Jewish community and beyond.
Police have indicated that the incidents share a "similar nature," with Israeli and Jewish premises being singled out. Deputy Assistant Commissioner Vicki Evans, speaking outside Kenton United Synagogue, explained that most of these attacks have been claimed online by the Ashab al-Yamin group, also known as the Islamic Movement of the Companions of the Right. This group has publicly taken responsibility for similar attacks on Jewish communities across Europe in recent months. "We are aware of public reporting that suggests this group may have links to Iran—as you would expect, we will continue to explore that question as our investigation evolves," Evans stated, as reported by BBC News.
Evans further elaborated on the tactics being used: "I've spoken previously about the Iranian regime's use of criminal proxies, and we're considering whether this tactic is being used here in London—recruiting violence as a service. Individuals carrying out these crimes often have no allegiance to the cause and are taking quick cash for their crimes." She warned that anyone identified in connection with these attacks could face prosecution under the National Security Act, which carries significant sentences and lifetime restrictions.
Deputy Commissioner Matt Jukes echoed these warnings, emphasizing that "thugs for hire who commit criminal acts and intimidation on behalf of others" would face long prison sentences. He made it clear that the authorities are determined to protect the community and bring those responsible to justice.
The response from community organizations has been swift and resolute. The Community Security Trust (CST), which provides security for Jewish people in the UK, said that the attack caused only minor smoke damage and that they are supporting the affected location while working closely with police. "We want to thank the Met Police and London Fire Brigade for responding quickly and for all they are doing to protect the Jewish community during this unprecedented period," a CST spokesperson said, as cited by The Independent.
The Campaign Against Antisemitism described the situation as "terrifyingly becoming a spate of daily arson attacks on the Jewish community." United Synagogue, the organization to which Kenton belongs, issued a statement saying, "A synagogue is not just a building, it is a place of worship, community and—theoretically—safety. To target it in this way is a deeply disturbing act that strikes at the heart of Jewish life." Saul Taylor, president of United Synagogue, urged the prime minister to publicly acknowledge what he called "an epidemic of anti-Jewish hate."
Chief Rabbi Sir Ephraim Mirvis has been vocal in his condemnation, calling the attack "cowardly" and warning that "a sustained campaign of violence and intimidation against the Jewish community of the UK is gathering momentum." In a statement shared on social media, he wrote, "This sustained attack on our community's ability to worship and live in safety is an attack on the values that bind us all together. Thank God, no lives have been lost, but we cannot, and must not, wait for that to change before we understand just how dangerous this moment is for all of our society."
The political response has been equally strong. Prime Minister Sir Keir Starmer expressed his outrage, stating, "I am appalled by recent attempted antisemitic arson attacks in north London. This is abhorrent and it will not be tolerated. Attacks on our Jewish community are attacks on Britain. We are increasing visible policing, and those responsible will be found and brought to justice. We will not rest in the pursuit of perpetrators." London Mayor Sadiq Khan echoed these sentiments, declaring, "There can never be any justification for attacking our Jewish friends, neighbours and colleagues. Those responsible are seeking to promote fear, hatred and division. They can't stand what our city represents—an open, diverse, pluralistic society that embraces and celebrates our differences."
In response to the attacks, the Metropolitan Police have stepped up patrols across northwest London. More officers have been deployed, including counter-terrorism units, and enhanced stop-and-search powers are in effect to deter further incidents and reassure the community. Forensic teams and fire investigation dogs have been seen combing the affected sites, while plainclothes officers gather evidence and monitor for potential threats.
The investigation has also expanded to include suspicious items found near the Israeli embassy in west London, including two jars containing powder. While the embassy itself was not attacked, authorities are probing whether these items are connected to a video posted by an Iran-linked Islamist group that claimed to have targeted the building with drones carrying dangerous substances.
As the investigation continues, the Jewish community remains on edge but determined not to be cowed. The attacks have drawn attention not only to the immediate threat but also to the broader issue of rising antisemitism and the need for vigilance and solidarity. The words of Chief Rabbi Mirvis resonate: "We cannot, and must not, wait for that to change before we understand just how dangerous this moment is for all of our society." The resolve of the authorities, community leaders, and everyday citizens will be tested in the coming weeks as they work together to ensure that London's values of safety, diversity, and unity remain unshaken.
