London synagogue arson attacks: Counterterror unit probes third incendiary incident in Harrow
Counterterror police have taken over the investigation into a series of London synagogue arson attacks after an incendiary device was thrown at the Kenton United Synagogue in Harrow, marking the third assault on Jewish sites in less than a week.
Kenton United Synagogue targeted in Harrow
Late on Saturday night an unknown attacker threw what police described as a fire‑starting device through a window at the Kenton United Synagogue in the Harrow area of north London. A patrol discovered the damaged window shortly after midnight and reported that the device caused localised damage but no major fire had taken hold.
The incident is the latest in a string of attacks on Jewish institutions across the capital that security sources say occurred over the course of the last week. Authorities have not reported any injuries linked to this latest episode while forensic teams began photography and evidence recovery at the scene.
Counterterror police assume lead on investigation
Scotland Yard’s counterterrorism command has assumed responsibility for the probe, reflecting concerns about a possible coordinated campaign targeting the Jewish community. Detectives told local police to bolster patrols near synagogues and community centres while specialists conduct house‑to‑house inquiries and forensic examinations.
Investigators are examining CCTV, witness statements and material recovered from the scene to establish a timeline and identify suspects. Officers warned that the inquiry remains live and appealed to members of the public with information or footage from the area to come forward.
Claims of responsibility by pro‑Iranian group
Most of the recent incidents have been claimed by a group identifying itself as Harakat Ashab al‑Jamin al‑Islamija, which describes itself in statements as aligned with pro‑Iranian causes. Police are treating those claims as part of the investigative picture but have not confirmed a direct organisational link to the perpetrators in Harrow.
Security analysts say claims of responsibility can be opportunistic and demand careful verification, and officers are therefore focusing on tangible evidence rather than statements circulating online. Authorities also stressed the importance of distinguishing between credible threats and propaganda designed to inflame tensions.
Religious leaders and prime minister condemn attacks
British Chief Rabbi Ephraim Mirvis warned of a wave of violence and called for vigilance across the community, urging synagogues and Jewish organisations to follow security guidance from police. Community leaders have expressed alarm at the frequency of the attacks and called for increased protective measures around houses of worship.
Prime Minister Keir Starmer issued a forceful condemnation on social media, calling the attempted antisemitic attacks “appalling” and saying they will not be tolerated. He framed assaults on the Jewish community as attacks on the country as a whole and pledged support for law enforcement efforts to bring those responsible to justice.
Police presence increased around Jewish sites
In response to the incidents, police have visibly increased patrols around synagogues and Jewish community centres in affected boroughs. Officers in uniform and plain clothes have been placed at key locations and liaison officers are coordinating directly with community security teams.
Local councils and faith groups are working together to review security arrangements for public events and services, and officials have urged places of worship to report any suspicious activity immediately. Authorities have also stressed that community safety depends on public cooperation, including the sharing of video or photographic evidence.
Investigative priorities and next steps
Detectives said their immediate priorities are to identify the individuals involved, establish whether the incidents are linked, and determine the veracity of online claims of responsibility. Forensic analysis of the device used in Harrow and digital leads from the scene are expected to play a central role in shaping the direction of the inquiry.
Police have not ruled out charging suspects once sufficient evidence is obtained and stressed that counterterrorism resources will remain committed to the investigation for as long as necessary. Senior officers are due to brief political leaders and community representatives as the probe progresses.
The investigation into the London synagogue arson attacks continues as authorities try to reassure a shaken community and prevent further incidents. The police appeal for information remains open, and officials say any new intelligence could prove crucial to stopping what leaders fear may be a sustained campaign of hostility.
