At least five camouflage-clad gunmen with automatic weapons burst into the packed concert hall in the Russian capital’s western suburbs on Friday night as the audience was gathering to watch the veteran rock band Picnic, shooting into the crowd and setting off explosives that started a massive fire.

ISIL, the hardline group that once sought control over Iraq and Syria, claimed responsibility for the attack on its Telegram channel, saying the gunmen had escaped. It was not possible to independently verify the claim.

At least 115 people have been confirmed killed, Russia’s Investigative Committee said on Saturday, adding that the number of victims was expected to rise further.

At least 187 people including eight children were injured.Health officials earlier said 60 of the injured were in critical condition.

On Saturday, a spokesperson for Russia’s Investigative Committee said it was too early to say anything about the fate of the attackers, state news agency RIA reported.

The concert hall, one of the most popular in Moscow, can hold some 6,200 people. “I realized right away that it was automatic gunfire and understood that most likely it’s the worst: a terrorist attack,” Alexei told the AFP news agency, declining to share his full name.

As people ran towards the emergency exits, “there was a terrible crush” with concertgoers climbing on one another’s heads to get out, he added. Another witness, speaking to the Reuters news agency, also described the terror and panic inside the venue.

“A stampede began. Everyone ran to the escalator,” they said, declining to share their name. “Everyone was screaming; everyone was running.” The attack, which left the concert hall in flames and its roof in a state of collapse, was one of the worst in Russia since the 2004 Beslan school siege in which more than 330 people, half of them children, were killed. The death toll appeared set to rise, according to unconfirmed reports.

Reporting from Moscow, Al Jazeera’s Dorsa Jabbari said that while the capital was not under lockdown or a curfew, “a number of events over the weekend here have been cancelled, including concerts”.

There was condemnation of the attack from across the world.

United Nations Secretary-General Antonio Guterres expressed his shock at the attack, which his spokesman said he “condemns in the strongest possible terms”, while the UN Security Council condemned what it called a “heinous and cowardly terrorist attack.”

French President Emmanuel Macron “strongly condemns the terrorist attack claimed by the Islamic State”, the Elysee Palace said.

“France expresses its solidarity with the victims, their loved ones and all the Russian people.”

Spain said it was “shocked” at events in Moscow, while Italian Prime Minister Giorgia Meloni condemned what she said was an “odious act of terrorism” and expressed her “full solidarity with the affected people and the victims’ families”.

Engulfed in flames

The Kremlin did not immediately blame anyone for the attack, but some Russian lawmakers were quick to accuse Ukraine.

Former Russian President Dmitry Medvedev wrote on the Telegram app that if those responsible for the attack turn out to be Ukrainian, “all of them must be found and ruthlessly destroyed as terrorists”.

Mykhailo Podolyak, an adviser to Ukrainian President Volodymyr Zelenskyy, denied Ukraine’s involvement.

“Ukraine has never resorted to the use of terrorist methods,” he posted on X. “Everything in this war will be decided only on the battlefield.”

Rosgvardia, Russia’s national guard, said it was searching for the perpetrators of the attack, and its units were helping evacuate concertgoers from the burning building.

Rescue services had evacuated about 100 people from the basement of the Crocus City Hall, but there are still people on the roof, Russian news agencies reported.

Media reports said firefighters were trying to contain the fire, as plumes of black smoke rose above the venue into the night sky.

Helicopters were also deployed in an attempt to douse the flames that had engulfed the building.

In the early hours of Saturday morning, authorities said most of the fire had been put out.

“There are still some pockets of fire, but the fire has been mostly eliminated. Rescuers were able to enter the auditorium,” Moscow Governor Andrey Vorobyov said on Telegram.

An ‘act of terrorism’

The prosecutor’s office said several men in combat fatigues had entered the concert hall, about 20km (12 miles) from the Kremlin and next to the Moscow ring road, and fired on those inside.

Repeated volleys of gunfire could be heard in videos posted by Russian media and on Telegram channels. One showed two men with rifles moving through the venue. Another showed a man in the auditorium saying the assailants had set it on fire, as repeated gunshots rang out in the background.

Others showed up to four attackers, armed with assault rifles and wearing caps, shooting screaming people at point-blank range.

Security guards at the concert hall were not armed, and Russian media said some could have been killed at the start of the attack.

ISIL, in a statement posted by its Amaq news agency, claimed its fighters had attacked on the outskirts of Moscow, “killing and wounding hundreds and causing great destruction to the place before they withdrew to their bases safely”.

Russia has reported several incidents involving ISIL this month, with authorities saying they killed six alleged members of the group in a shootout in Ingushetia in the restive Caucasus region, and the Federal Security Service (FSB) saying on March 7 it foiled an attack by Islamic State in Khorasan Province (ISKP), an Afghan affiliate of ISIL, on a Moscow synagogue.

The United States had also warned of a heightened threat. Several hours after the FSB announcement, the US embassy in Moscow issued a warning that “extremists” had imminent plans for an attack in Moscow. On Friday night, a US official said Washington had intelligence confirming ISIL’s claim of responsibility for the attack on Crocus City Hall.

Earlier, Russian Foreign Ministry spokeswoman Maria Zakharova said what had happened was a “bloody terrorist attack”. Investigators from Russia’s Investigative Committee, which deals with major crimes, said they had “opened a criminal probe under article 205 of the criminal code [terrorist act]”.
