Following an attack on a Moscow performance hall, dozens of people are dead and numerous others are injured.

On Friday, a group of shooters dressed in camouflage broke into a concert venue on the outskirts of Moscow, leaving at least 60 dead and 145 injured. Flames from a fire could be seen for kilometers after it started. Nobody knows the gunmen's whereabouts.

A government official told NPR that the United States believes Islamic State Khorasan Province, or ISIS-K, is to blame. The eastern Afghanistan-based gang took credit for the incident on its Telegram channel.

National Security Council spokeswoman Adrienne Watson said in a statement that the United States had informed Russia earlier this month about a planned terror act in Moscow that might have targeted concerts.

A group of armed gunmen dressed in military fatigues entered the Crocus City Hall venue in Moscow, where fans had gathered to watch the seasoned Russian rock band Picnic.

At least three attackers can be seen firing at onlookers as they try to hide in witness videos posted on social media. In other photos, individuals are seen lying on the floor of the main music hall just before a fire starts and spreads, trapping some people inside. On the roof of the venue, several persons were observed.

Mayor Sergey Sobyanin of Moscow offered his condolences and stated, "A huge tragedy has occurred" as the death toll is predicted to climb.

The Ukrainians refute the suggestion made by certain Russian authorities that there must be a role for them. Volodymyr Zelenskyy's counselor, Mykhailo Podolyak, tweeted, "Ukraine definitely had nothing to do with the shooting in the Crocus City Hall." It is completely nonsensical."

In a statement, the White House described the attack as "terrible" and stated that there was "no indication at this time" that Ukraine was involved in the attack.

Spokesman for the National Security Council John Kirby described the shooting's photos as "horrible and hard to watch." The American consulate in Moscow has advised its nationals to stay away from the region.

In 2002, a hostage situation occurred in Moscow at the Dubrovka theater, as Chechen terrorists demanding the withdrawal of Russian soldiers from Chechnya held some eight hundred theatergoers hostage. To put an end to the issue, 172 individuals were killed or made to die in a raid by Russian security forces.

Maria Zakharova, a spokesman for the Russian Foreign Ministry, urged nations to denounce the event as "a monstrous crime."
