The arson attacks have targeted various Jewish sites, including synagogues and community ambulances. Notably, the Kenton United Synagogue was attacked, resulting in minor damage but no injuries.

While the police have arrested 25 individuals, the specific motivations and affiliations of those involved remain unclear. There are indications of a potential connection to Iranian-backed groups, but no direct evidence has been established linking the arrests to these organizations.
