The death toll of the Crocus Concert Hall attack has now risen to 133, the Russian Investigative Committee says.
As the emergency services are continuing to clear rubble at the venue, they are continuing to find more bodies, the committee says in a post shared on the Telegram messaging app.
A further 107 people are recovering in hospital, it added.
Gunmen stormed the concert hall on the outskirts of Moscow and opened fire on the crowd, the head of Russia's Federal Security Service told President Vladimir Putin.
The attack was the deadliest in Russia in years.
The Moscow city and regional governments said they would provide financial support for the families of the victims and those injured and pay for funerals.
