Britain bans support for Iran’s Islamic Revolutionary Guard Corps (IRGC) and another Iran-linked group after a series of antisemitic attacks in the country, according to multiple reports citing Reuters. The UK government applies new powers intended to prevent the use of state-sponsored proxies. The measures are designed to “proscribe-like” effect, effectively outlawing support for the targeted groups and expanding the ability of police and intelligence agencies to act on threats connected to them. The action follows growing concerns within government and intelligence services that foreign powers may work through or pay intermediaries—such as organized crime groups or low-level criminals—for surveillance, sabotage, or other harmful activities. Reuters and other outlets report that the ban is part of a wider effort to respond to foreign-state-linked violence and to address risks connected to antisemitic incidents targeting Jewish-linked sites. The reports describe the decision as a step to strengthen counter-proxy capabilities rather than a direct response to a single attack, and they note the government’s stated focus on disrupting state-backed networks.
