Speculation about who carried out the shooting at the Crocus City Hall in Moscow has quickly indicated that the terror attack will have outsized political implications in Russia and abroad.

A claim has surfaced that the attack was carried out by Islamic State Khorasan Province (ISKP) a regional affiliate of the IS terrorist organisation. IS has been implicated in some of Russia's largest recent terror attacks, including the 2017 bombing in the St Petersburg metro that killed 15 and injured 45.
