Gunmen attacked Moscow’s Crocus City Hall concert venue in March, killing 137 people. The four suspects were purportedly aligned to the militant terrorist organisation Islamic State-Khorasan (IS-K).
IS-K is an affiliate of the Islamic State militant group and seeks to create a territorially unbound caliphate. Its militants have launched violent attacks in Afghanistan, especially on ethnically Hazara Shia Muslims, as well as on high-profile targets in Iran and Pakistan. The group’s deadly attacks have ensured that the term Khorasan is now globally associated with Islamist militancy.
