A teenager detained on suspicion of carrying out a terrorist attack at a school in Odintsovo, Moscow Region, who killed a 10-year-old Tajik boy, has confessed and described the preparation and details of the crime. This was reported by the Russian Investigative Committee.

According to investigators, the 15-year-old student spent a week preparing for the attack. During this time, he wrote an 11-page manifesto, "My Anger," in which he described his hatred of people and divided them into ethnicities and religions. Ultimately, he intended to kill a teacher and stabbed the 10-year-old Tajik boy to death.

The horrific attack occurred on the afternoon of Tuesday, December 16, at Uspenskaya Secondary Comprehensive School in Odintsovo. The attacker, a 15-year-old ninth-grader, arrived at the school with a knife and wounded a security guard and several students. A ten-year-old fourth-grade student was killed, and a security guard was taken to the hospital. Before the brutal attack, the teenager reportedly asked a Tajik boy, "What nationality are you?" The attacker was detained by security forces.

The teenage killer was a fan of the international neo-Nazi movement No Lives Matter.
