By William JamesLONDON, July 13 (Reuters) - Britain banned support for Iran's Islamic Revolutionary Guard Corps and a linked group on Monday following a series of antisemitic attacks, using new powers designed to stop the use of state-sponsored proxies.The government and intelligence agencies have become increasingly concerned about foreign powers paying organised crime groups or low-level criminals for surveillance, sabotage or other activities on their behalf.

The U.K. government says a proxy group backed by Iran is responsible for recent arson and vandalism attacks on Jewish sites in Britain.

Britain says the Islamic Movement of the Companions of the Right claimed seven arson and vandalism attacks in the UK and was almost certainly directed by the IRGC’s Quds Force
