"Allegations of Abuse Surface in Moscow Attack Suspects' Arrest"

A deadly attack at a Moscow-area concert venue claimed by the Islamic State (IS) militant group has left 133 dead and over 120 wounded, with four suspected gunmen detained. Russian officials have condemned the attack as a "bloody, barbaric terrorist attack," and President Vladimir Putin has called for preventing further crimes. The Kremlin has remained silent on suspicions of abuse of the suspects. Mourners have created makeshift memorials across Russia, and there are discussions about reinstating capital punishment in response to the attacks. The identities and motives of the attackers remain unclear, and world leaders have condemned the violence.
