Moscow attack: Russia detains 11; death toll hits 133

Moscow: Russian President Vladimir Putin said Saturday that authorities have detained 11 people in the attack on a suburban Moscow concert hall that killed at least 133 people and left the sprawling venue a smoldering ruin.

In an address to the nation, Putin called it “a bloody, barbaric terrorist act” and said all four people who were directly involved had been taken into custody.

He suggested they had been trying to cross the border into Ukraine which, he said, tried to create a “window” to help them escape. Ukraine has strongly denied any involvement in the attack.

Putin said Saturday that additional security measures have been imposed throughout the country and declared March 24 a day of national mourning.
