"Unraveling the Moscow Concert Hall Terror Attack: ISIS-K, Suspects, and Intelligence Agencies"

ISIS-K, an affiliate of the Islamic State group, claimed responsibility for the deadly assault on a concert venue in Moscow, which left at least 137 people dead and more than 100 injured. The group, active in Afghanistan, Pakistan, and Iran, aims to create a "pure Islamic state" and has a mutual hatred of the Taliban and the West. ISIS-K has been linked to various attacks, including the Kabul airport bombing, and has drawn global concerns about its potential to pose a major threat across the region and beyond. The group's recent attack in Moscow has raised tensions between Russia and the US, with Russian President Vladimir Putin rejecting US embassy warnings about terror attacks and suggesting Ukraine's involvement.
