A video, purportedly by the Moscow concert hall attackers, emerged on IS-associated social media. Gunmen, armed with rifles and knives, are seen amidst bodies and fire at Crocus City Hall. IS’s Amaq Telegram account posted the video, claiming responsibility for the assault that left 133 dead. Kremlin reports 11 arrests, including the four main suspects heading to Ukraine. Putin and FSB haven’t directly blamed IS, while Kiev denies involvement. RT released interrogation videos of two suspects admitting to the attack. AFP couldn’t verify their authenticity.
