Britain's government on ‌Monday targeted Iran's Islamic Revolutionary Guard Corps and another Iran-linked group after a string of antisemitic attacks on British streets, using proscription-like powers designed to tackle ‌state-backed threats.

The power would effectively ​outlaw support for those groups and give police and intelligence agencies new ⁠powers to tackle any threats linked to ​them.

"These new powers will make it easier ⁠to prosecute and lock up anyone carrying out their dirty work here in Britain," Prime Minister Keir ‌Starmer said in a statement.

The IRGC, ​which is ‌already subject to British sanctions, has served as an elite ‌military force loyal to the Islamic Republic's Supreme Leader since being established after the ⁠1979 Islamic Revolution.

Britain said ‌the second Iran ⁠linked-group, the Islamic Movement of Companions of the ⁠Right, ⁠had claimed seven attacks linked to Jewish and Israeli communities, and ‌Persian-language media, including the antisemitic arson attack on four Hatzola ambulances in Golders Green on March ‌23.

Britain ​also designated ‌Russia's GRU intelligence agency under the new powers.

The designations need to be approved ​by parliament before the take effect.
