Shiite Muslim terrorists, unlike Sunni Muslim terrorists, tend to operate around the unified command and control hub of Iran. They’ve spent more time laying the groundwork for future attacks, recruiting operatives and engaging in criminal operations meant to move money around including dealing drugs.

What does it mean that the network is being operationalized for terrorist attacks?

A suspected Iranian terror attack was hours away from being launched on British soil, The Telegraph understands.

Five men, including four Iranian nationals, were arrested at locations across England on Saturday in what the Home Secretary described as one of the biggest counter-terror operations in recent years.

Counter-terror police arrested a further three Iranian men in London as part of a separate operation, fearing they would leave the UK or destroy critical evidence against them after the other raids.

Iran has recruited operatives for assassinations in the U.S. targeting former Trump administration officials and Salman Rushdie, a longstanding target, but don’t expect anyone in the British government to talk about it.

On Sunday night, there were renewed calls for Labour to proscribe Iran’s Islamic Revolutionary Guard Corps (IRGC).

Despite having pledged in opposition to ban the organisation, Labour have yet to do so.

The Telegraph understands that Foreign Office officials have previously opposed the move because it would prevent the UK from maintaining its backchannel to Iran, which is also used by the United States.

The IRGC is Iran’s terror hub, but the sort of political interests who favor talking to Iran over national security refuse to do it.
