At Crocus City Hall, near Moscow, an assault was initially planned but had to be altered due to a malfunction in the attackers' rifles.
Details emerged about the tragic event in an article from the Islamic State's newspaper "Al-Naba."
The plan involved three attackers opening fire on people inside the venue, while a fourth was designated to ignite the building, creating obstacles for rescue efforts.
The attackers intended a more extensive assault, with sufficient ammunition to kill more individuals and confront responding security forces.
However, due to malfunctioning rifles, they were compelled to withdraw and were ultimately surrounded in a forest and taken into custody.
The newspaper suggested that after Russian authorities failed to thwart the attack, they blamed the "Western camp" to avoid admitting defeat by the militants.
"Al-Naba" also mentioned that Russia aims to interrogate the captives in a manner that fuels political disputes with its adversaries and obscures the losses inflicted by the militants, asserting that the assault resulted in over 500 casualties, either killed or injured.
Russia has pointed fingers at Ukraine, but experts challenge this narrative, highlighting previously unknown details within the reports.
Vladimir Putin has maintained that Islamists have no motive for targeting Russia, asserting that the country seeks a "fair solution" to the intensifying Middle East conflict.
It is crucial to remember that Russian forces, including soldiers and mercenaries, are actively engaged against jihadist elements globally, including in Africa.
Furthermore, Moscow continues to back Bashar al-Assad's regime in Syria, which is in conflict with the Islamic State.
