The rescue operation on the scene of the Moscow attack is over, according to Moscow Oblast Gov. Andrey Vorobyov.
The search for victims at the concert hall is ongoing.
"Today rescuers cleared a huge layer of the auditorium," Vorobyov said in a statement on Telegram. "Over the course of 24 hours, 133 bodies were pulled out from under the rubble, and the identities of 50 dead were tentatively identified."
Officials have not publicly released the identities of the 50 victims.
"At night we will start creating an opening on the western side of Crocus, this will make it easier to access the concert hall," Vorobyov said.
The National Security Council said today in no uncertain terms that Ukraine had nothing to do with the deadly concert attack.
"ISIS bears sole responsibility for this attack. There was no Ukrainian involvement whatsoever," NSC spokesperson Adrienne Watson said in a statement.
