We’ve just received the full statement from the Russian Investigative Committee, which in addition to upping the death toll to 93, and warning that that number might rise, said:

• The concert hall is still being inspected, with emergency services working to clear the rubble, seize evidence and go through CCTV footage
• The attackers used flammable liquid to set fire to sections of the concert hall
• The causes of death of the 93 victims were gunshot wounds and poisoning by combustion products
• The attackers are believed to have used automatic weapons, leaving behind ammunition
• Ballistic, genetic and fingerprint examinations are now being carried out

At least 93 people are dead and more than 140 have been wounded after gunmen open fired at a rock concert at Crocus City Hall in a suburb of Moscow on Friday evening local time, Russian intelligence says

The US says it’s credible that an affiliate of the Islamic State group could be behind the attack, after the group said they carried out the attack.

The White House also says it warned Russia of a potential attack on “large gatherings” in Moscow earlier this month. Russia has not commented
Ukraine – currently at war with Russia – has denied any involvement

The Kremlin says Putin has been briefed on what happened – he has not addressed the nation directly, but according to a deputy has wished those injured a speedy recovery
Security has tightened across Russia, with events cancelled as the country’s national guard searches for the attackers and dispatches its investigators to the site.
