According to the report, published on Friday the attackers underwent professional training and demonstrated advanced weapons skills. The information was confirmed to TASS by a source at the Second Western District Military Court.
A person involved in the judicial proceedings said all of the defendants had received training and possessed professional-level proficiency in the use of firearms. The source said one of the accused, Shamsidin Fariduni, displayed a high level of marksmanship during questioning in court.
The source also suggested that two separate operational groups had been prepared for the attack and later merged. The defendants have denied this claim.
According to the TASS report, Fariduni had initially been expected to travel via mountainous routes from a base in Türkiye to Afghanistan to join Islamic State Khorasan Province. However, because those routes were closed during the winter, he was allegedly instructed instead to take part in the Crocus City Hall attack.
Based on court information cited in the report, Fariduni was tasked with recruiting accomplices inside Russia, conducting reconnaissance at the Crocus City Hall, purchasing a vehicle to transport the attackers and obtaining weapons. During initial interrogations, he reportedly said the group did not intend to kill children, though Russian judicial authorities said the evidence does not support that assertion.
The report added that the organisers of the attack promised the perpetrators a payment of one million roubles. After carrying out the assault, the attackers reportedly headed toward Ukraine, where the money was to be paid.
The attack took place on March 22, 2024, in the Moscow suburbs. Four armed assailants opened fire on the crowd shortly before a concert began and then set the venue on fire. At least 149 people were killed and more than 600 others wounded in what was one of the deadliest terrorist attacks in Russia in recent decades.
The Islamic State claimed responsibility for the attack. Court proceedings against the suspects began in the summer, with the four main defendants appearing in court after being arrested shortly after the assault.
