The Metropolitan Police have detained a 17-year-old boy and a 19-year-old man in connection with the arson assault on Kenton United Synagogue in Harrow, north-west London, on Sunday.
A man was spotted igniting a bag in the doorway, which was later discovered to contain three bottles containing liquids. The shopfront sustained minor damage, but no injuries were recorded.
We are seeing a concerted campaign against Londoners and, specifically, against British Jews.
Authorities claimed the latest incident occurred overnight at Kenton United Synagogue in Harrow. The structure experienced smoke damage, but no one was injured, according to officials.
Series of Arson Attacks Targeting Jewish Sites
According to Metropolitan Police deputy commissioner Matt Jukes, 15 people have been arrested in connection with a series of six incidents in which Jewish-owned businesses in London have been attacked in recent weeks. Counter-terrorism officials are investigating fires against synagogues and other Jewish-related facilities, as well as an attack on a Persian-language media outlet. No one was wounded in the blazes, which occurred within a few miles of each other.

The most catastrophic incident occurred on March 23, when four ambulances belonging to a Jewish charity were set on fire in the Golders Green district. The Finchley Reform Synagogue was set on fire, and a company in northwest London was also targeted in what police called an antisemitic hate crime. Authorities say they are witnessing a deliberate effort against Londoners, notably British Jews.
This latest arson at Kenton United Synagogue marks the third similar event in the past week, adding to growing concerns over repeated targeting of Jewish community sites across northwest London.
Police continue to search for connections between the incidents while extra officers have been deployed to the area to reassure the public.
The Jewish community in the UK has expressed deep unease as these attacks persist without causing any physical injuries but creating significant fear and a strong sense of intimidation, leaving many feeling unsafe in their own neighbourhoods and places of worship despite the visible increase in police presence.
