Between June and 30 October this year, the monitoring group recorded 30 separate reports, marking the highest figure in over a decade.
Tell MAMA says these cases involved attacks, vandalism and threatening behaviour toward religious sites.
According to Iman Atta, director of the organisation, there is a persistent and deepening problem of anti-Muslim hatred. She warns that these attacks not only undermine social cohesion, but may also be driven by extremist ideologies.
The surge in mosque-targeted hate coincides with broader trends in anti-Muslim incidents. In 2024, Tell MAMA logged over 6,300 verified cases, the highest since its founding, including a sharp rise in threatening behaviour.
Data for June to September 2025 show Tell MAMA documented 913 reports of anti-Muslim hate, of which 17 were linked to mosques or Islamic institutions.

This spike follows heightened tensions in recent years, including after the October 2023 Israel-Gaza war and other high-profile events, which the group says have fuelled hostility toward visibly Muslim communities.
One of the latest incidents is a suspected arson attack on a mosque in Peacehaven, East Sussex. Police are investigating the incident. Two masked men poured a flammable liquid at the entrance and set fire to the building and a car, though no injuries were reported.
The rise in attacks has prompted calls for stronger protection and funding for Muslim places of worship. While the UK government has increased security grants for mosques in recent years, community leaders and watchdogs argue that more sustained action is needed in light of the escalating threat.
