Islamic State claims members escaped after attacking concert hall The Islamic State have claimed responsibility for the attack on the Crocus City Hall on the outskirts of Moscow. The full statement posted on its Telegram account reads: Islamic State fighters attacked a large gathering of Christians in the city of Krasnogorsk on the outskirts of the Russian capital, Moscow, killing and wounding hundreds and causing great destruction to the place before they withdrew to their bases safely. The US has intelligence confirming the Islamic State’s claim taking responsibility for the attack, according to Reuters. The agency cites an unnamed US official: The official said the United States had warned Russia in recent weeks about the possibility of an attack. ‘We did warn the Russians appropriately,’ said the official, speaking on condition of anonymity, without providing any additional details. At least 40 people were killed and 145 wounded on Friday when camouflage-clad gunmen opened fire with automatic weapons on concertgoers near Moscow in one of the deadliest attacks on Russia in decades. Islamic State, the militant group that once sought control over swathes of Iraq and Syria, claimed responsibility for the attack, the group’s Amaq agency said on Telegram. The death toll made it one of the worst attacks on Russia since the 2004 Beslan school siege, when Islamist militants took more than 1,000 people hostage, including hundreds of children. The death toll has risen to 62, Russia’s Baza news outlet has reported based on preliminary information. The Guardian has not confirmed the number and will be watching for updates from the health ministry. Russia’s president Vladimir Putin has yet to make a public comment on the attacks. The Kremlin has said he is receiving regular updates. UN secretary general condemns attack in "strongest possible terms" The United Nations secretary general António Guterres has condemned the attack “in the strongest possible terms”, a spokesperson said. “The secretary general conveys his deep condolences to the bereaved families and the people and the government of the Russian Federation. He wishes those injured a speedy recovery,” said deputy spokesperson Farhan Haq. As the Russian national guard continues to secure the area, Russians have begun to mourn those who died in the attack. People at the concert describe a chaotic scene as the attack began. Alexei, a music producer, told AFP he had been about to settle into his seat before the concert, when he heard “several machine gun bursts” and “a lot of screams”. “I realised right away that it was automatic gunfire and understood that most likely it’s the worst: a terrorist attack,” he said. Another witness told Reuters that a stampede began as everyone rushed away from the gunfire. “A stampede began. Everyone ran to the escalator,” the witness said. “Everyone was screaming, everyone was running.” CNN’s chief national security correspondent writes that sources have revealed that there may have been specific intelligence indicating an imminent attack. Isis-K refers to the Islamic State of Khorasan Province, active in south-central Asia.The Islamic State appears to have taken credit for the attack via a Telegram post. 145 people injured in attack, says Moscow health ministry The number of people wounded in the attack at the Crocus City Hall in Krasnogorsk near Moscow has been revised to 145, Russia’s Tass state news agency is reporting, citing figures by the Moscow region’s health ministry. At least two children have been wounded in the attack at the Crocus City Hall, according to Russia’s commissioner for children’s rights, Maria Lvova-Belova. Lvova-Belova, in an interview aired by Russia’s state-owned Rossiya-24 channel, said: There are wounded children, not many of them so far. There is a boy with a gunshot wound, but all are in a moderately grave condition so far … There is a boy who was struck with the buttstock of a rifle, in a stable condition. The Russian national guard have completed an inspection of the parking lots around the Crocus City Hall and have found no explosives, a Russian MP has said. In a Telegram post, lawmaker Alexander Khinshtein added that members of the national guard are continuing their checks of the surrounding area. The European Union is “shocked and appalled” by the reports of a terrorist attack in the Crocus City Hall, the bloc’s lead foreign affairs spokesperson Peter Stano has said. Posting to social media, Stano said the EU “condemns any attacks against civilians”.
