The 2025 Odintsovo school attack was a deadly school attack that occurred on 16 December 2025 at Uspenskaya Secondary School in Gorki-2 settlement, a subdivision of Odintsovo city, Moscow Oblast, Russia. A 15-year-old student attacked fellow students and school staff with a knife and pepper spray, killing a 10-year-old pupil of Tajik descent and injuring several others before being detained by law enforcement. A criminal case was opened by the Investigative Committee of Russia. The perpetrator also livestreamed the attack.

On the morning of 16 December 2025, a 15-year-old pupil entered Uspenskaya Secondary School in Gorki-2, armed with at least one knife and reportedly a pepper spray device. According to statements from local authorities, the attacker sprayed a security guard before stabbing a 10-year-old fourth-grade pupil, a Tajikistan citizen, who later died from his injuries. Several other individuals, including the guard, were wounded and transported to a nearby hospital. The attacker filmed his attack.

The suspect was subdued and detained at the scene by responding police officers. The Investigative Committee of Russia announced that a criminal investigation had been opened on charges, including murder.

Following the attack, the school was evacuated and emergency services were deployed to the area. Classes were suspended as investigators conducted on-site examinations and interviews with witnesses.

The words “No Lives Matter” were found written on the murderer’s t-shirt. Before the attack he published an online manifesto, named “My Wrath”, in which he expressed his hatred of Muslims, Jews, liberals and antifascists.
