The article's claim that this probes an attack after antisemitic attacks is supported by the provided search results. ## London Synagogue Arson: Counterterror Probe Escalates *UK counter-terrorism forces are investigating a fire at a former London synagogue, part of a surge in antisemitic incidents that has led to a terror threat level increase.* **Counter-terrorism police are investigating an arson attack that occurred early Tuesday, May 5, at a former synagogue in London’s Tower Hamlets.** The fire caused minor damage to the building’s entrance. While the targeted building is no longer in use as a synagogue, the incident has amplified fears within the Jewish community, especially given the **recent increase in antisemitic incidents** across the UK. This event follows a series of attacks, including a stabbing that injured two Jewish men in Golders Green on April 29. The UK’s terrorism threat level was raised to "severe" on April 30, the first time in four years, underscoring the heightened security environment. This probe is part of a larger investigation into a wave of arson attacks, which has led to **23 arrests** by Counter Terrorism Policing London, with inquiries focusing on the potential use of "criminal proxies" by foreign states, including Iran.
