The US's Department of Homeland Security (DHS) is reviewing security grants to Muslim organisations and places of worship that have been accused by a pro-Israel think tank of having ties to "radical" groups.

The department has already cut an estimated $8m across 49 projects for alleged affiliations to terrorist activities, according to a DHS document obtained by Fox News.

The DHS is said to be basing its decision on a report from the Middle East Forum (MEF), which claims that the DHS gave $25m in grants to "radical nonprofit organisations", many of which it accuses of having "links" to terrorist groups, from 2013 to 2023.

The grants come from the Federal Emergency Management Agency (Fema) to help state, local, tribal and nonprofit organisations to prevent, protect against, prepare for and respond to hate-based terrorist or extremist attacks.

Mosques and other faith-based groups have received funding from Fema to help enhance their security.
