A synagogue in north-west London has been targeted in the latest of a series of arson attacks on Jewish sites in the British capital, causing minor smoke damage but no injuries, according to the Community Security Trust (CST), which monitors antisemitism and provides security advice to Jewish communities.

The incident at Kenton United Synagogue in Harrow occurred on Saturday night, the CST said in a statement. A spokesperson described it as 'another attempted arson' following similar recent incidents in Finchley, Golders Green and Hendon. Police cordoned off the area on Sunday morning, with forensic officers and fire investigation dogs seen at the scene.

Prime Minister Keir Starmer condemned the attack, saying he was 'appalled' by the spate of incidents. 'This is abhorrent and it will not be tolerated,' he wrote on X. 'Attacks on our Jewish community are attacks on Britain.' He vowed that authorities would 'not rest in the pursuit of perpetrators.'

Coverage Comparison

Reports of the attack have been carried by multiple outlets with varying emphasis. France 24 focused on the government's response, quoting Starmer and the Chief Rabbi. The Guardian highlighted Starmer's promise to proscribe Iran's Revolutionary Guards, a pledge that has not been reported by all outlets. The Jerusalem Post led with the incident details and the claim of responsibility by a pro-Iranian group, while also noting the police investigation and community response.

All sources agree on the core facts: the attack occurred on Saturday night, caused minor smoke damage, and no one was injured. The Metropolitan Police have stepped up patrols in areas with large Jewish populations amid an upsurge in antisemitic incidents.

Key Claims

  • Arson attack details: The Kenton United Synagogue in Harrow was targeted on Saturday night, causing minor smoke damage to an internal room but no injuries or significant structural damage, as reported by multiple sources citing the Community Security Trust.
  • Prime Minister's response: Keir Starmer said he was 'appalled' by the attacks and vowed to bring perpetrators to justice, according to reports from France 24 and other outlets.
  • Chief Rabbi's warning: Ephraim Mirvis said 'a sustained campaign of violence and intimidation against the Jewish community of the UK is gathering momentum,' a statement carried by multiple sources.
  • Arrest and plea: A 17-year-old boy pleaded guilty to arson not endangering life at Westminster Magistrates Court, according to a single source (The Guardian). This has not been independently confirmed.
  • Claim of responsibility: An Iran-linked group, Harakat Ashab al-Yamin al-Islamia, claimed responsibility for the attack, as reported by The Guardian and the Jerusalem Post. This claim has not been independently verified.
  • IRGC proscription promise: Starmer has promised to introduce legislation to proscribe Iran's Revolutionary Guards in the next parliamentary session in July, a pledge reported by The Guardian. The UK rejected such a move in 2023, and the EU listed the IRGC as a terrorist organisation in January.
  • Rise in antisemitic incidents: The CST identified 3,700 antisemitic incidents in 2025, according to one report. There has been a significant increase since the 7 October attacks and the ensuing war in Gaza, though this figure has not been corroborated by other sources in the available material.

Perspectives

Government response: Prime Minister Starmer described the attacks as 'abhorrent' and emphasised that attacks on the Jewish community are attacks on Britain. He has linked the incidents to 'malign state actors' and proposed new legislation to proscribe the IRGC, a move that has been welcomed by some but criticised as overdue.

Community concerns: The Chief Rabbi and the Community Security Trust have voiced alarm at the frequency of attacks. The CST thanked police and fire services for their rapid response, while the Campaign Against Antisemitism called the situation a 'cataclysmic failure' of the state to tackle antisemitic extremism.

Iranian involvement: Several sources, including The Guardian and the Jerusalem Post, highlight the claim of responsibility by an Iran-linked group and broader concerns about Iranian proxy activity. Phil Rosenberg of the Board of Deputies of British Jews linked the attacks to threats from 'Iranian actors' and expressed solidarity with Iranian dissidents.

Context of rising antisemitism: Reports note a broader increase in antisemitic incidents in the UK since the October 2023 attacks and the subsequent conflict in Gaza, with the CST recording thousands of incidents. This has been cited as the backdrop to the recent spate of arson attacks.
