The US government has claimed that all evidence points to an Afghanistan-based offshoot of the terrorist group Islamic State (IS, formerly ISIS or ISIL) as the mastermind behind the Crocus City Hall massacre on March 22. Any Russian suggestions to the contrary are “nonsense and propaganda”, White House National Security Communications Adviser John Kirby claimed last week.

Speaking at an international event in Astana, Kazakhstan, on Wednesday, Patrushev said Washington is determined to “impose” its preferred narrative regarding the attack.

“Identifying the mastermind and sponsor of the monstrous crime is what is most important. The trace leads to the Ukrainian special services,” he claimed.

“It is well known that the Kiev regime is not independent and is fully controlled by the US. We should also take into account that ISIS, Al-Qaeda and other terrorist organizations were created by Washington,” the senior official added.

The US role in “creating” the two terrorist organizations is a matter of debate, including in America itself.

Donald Trump infamously described then-President Barack Obama as the “founder of ISIS” during his 2016 White House campaign, while branding fellow candidate Hillary Clinton as the “co-founder” of the group.

IS arguably managed to emerge as a major threat in 2014 due to the US destabilization of Iraq and Syria, which radicalized sections of the population in both nations and undermined the ability of their governments to keep militants in check. The US and Russia have both since played a role in quashing IS.

Russian officials have suggested that ISIS-K, the group that claimed credit for the Crocus City Hall attack, now serves as a US tool, launching strikes at Washington’s opponents, including Iran and the Taliban government in Afghanistan. US officials deny the allegations.

The Crocus City massacre saw a group of gunmen shoot their way into the main hall of the music venue, setting it on fire and killing more than 140 people. They were caught hours later in a Russian region bordering Ukraine, where they were allegedly heading to escape pursuit.

Washington issued a public warning about an imminent attack in Russia in early March, weeks before the Crocus City assault. US officials have claimed a more detailed private alert was given to Russian law enforcement, although Moscow has said the tip was not sufficient to identify and stop the terrorists.

Unnamed US officials interviewed by the paper claimed that Russian authorities had been issued with a notice with a “high degree of specificity” one day before the US Embassy’s public warning on March 7.

At the time, the US mission advised Americans in the Russian capital to avoid large events in the next 48 hours, citing “reports that extremists have imminent plans to target large gatherings in Moscow, to include concerts”.

The White House has also claimed that it shared information about a potential attack with Russian authorities. The head of Russia’s Foreign Intelligence Service (SVR), Sergey Naryshkin, has confirmed this, but noted that “the information was too general and did not allow us to fully identify those who participated in this terrible crime”.

The New York Times reported last week that while the US had shared data on a terror threat, “the adversarial relationship” between the two countries – which is largely due to the Ukraine crisis – prevented full disclosure. US officials withheld some information “out of fear Russian authorities might learn their intelligence sources or methods”, the newspaper added.

The WaPo has also claimed that the US provided Moscow with information about plans by Islamic State (IS, formerly ISIS or ISIL) terrorists to stage an attack on a synagogue in Moscow. On March 7, Russia’s Federal Security Service (FSB) announced it had prevented an attack on a Jewish religious site, saying the terrorists had been killed in a gunfight while resisting arrest.

The attack on Crocus City Hall occurred on March 22, when a group of gunmen stormed the venue ahead of a rock concert, killing at least 144 people and injuring around 200 others. Several suspects, including four directly involved in the shooting, were detained by Russian security services within hours of the tragedy.

Russian President Vladimir Putin has claimed several terrorists were caught fleeing towards Ukraine, where “a window” to cross the border was being arranged for them.

Russian officials have argued that the Ukrainian intelligence services may have masterminded the plot, although Kiev has vehemently denied any involvement. The US and its allies have insisted that the attack was orchestrated by IS. Moscow has voiced suspicion over Western attempts to absolve Ukraine of any responsibility before the investigation is complete.
