Putin Vows Revenge For "Bloodbath" Moscow Attack, Points Finger At Help From Ukraine, As 11 'Terrorists' Captured

The official death toll from Russian authorities in the wake of Friday's terror attack on a Moscow concert hall has reached 133 killed, with some unofficial reports saying there could be as many as 140 or more. As the scene continues to be processed and investigated, and given some of the hospitalized are in critical condition, the death toll is likely to rise. Over 150 were wounded in the attack, which involved a group of well-equipped attackers sporadically shooting into crowds as they walked through the mall and into the concert hall. Three children are still in the hospital, with one in critical condition.

The mall and complex at the Crocus City Hall music venue appears to have burned for many hours through the night. Russia's Investigative Committee later said more bodies were recovered from be smoldering building. Importantly, authorities on Saturday announced the capture of four suspected gunmen, also amid unconfirmed social media videos purporting to show some of the detained alleged gunmen.
