At least 17 people, including 11 children and the attacker, were reported killed in a school shooting in the city of Izhevsk in central Russia, the country's Interior Ministry said Monday.
According to Russia's Investigative Committee, 24 other people, including 22 children, were wounded in the attack.
Russia's Investigative Committee identified the gunman as 34-year-old Artyom Kazantsev, a graduate of the same school, and said he was wearing a black T-shirt bearing "Nazi symbols." No details about his motives have been released.
Investigators have said two security guards and two teachers were among the victims, while the attacker "committed suicide."
Rescue and medical workers could be seen in the background, some running inside the school with stretchers immediately after the incident was reported.
Russia's Health Ministry said "14 ambulance teams" were working at the scene to help the injured, news agencies reported.
The attack was the latest in a series of school shootings that have shaken Russia in recent years and came with the country on edge over efforts to mobilize tens of thousands of men to fight in Ukraine.
Russian President Vladimir Putin denounced the "inhuman terrorist attack" in the city of Izhevsk, the Kremlin said, adding that the shooter "apparently belongs to a neo-fascist group."
Investigators said they were conducting a search of Kazantsev's home and looking into his "adherence to neo-fascist views and Nazi ideology."
Brechalov declared a period of mourning in the region to last until Thursday.
A city of around 630,000 people, Izhevsk is the regional capital of Russia's Udmurt Republic, located around 1,000 kilometers (620 miles) east of Moscow.
The attack came just hours after a man had opened fire and severely wounded a recruitment officer at an enlistment center in Siberia.
Russia's last major school shooting was in April, when an armed man opened fire in a kindergarten in the central Ulyanovsk region, leaving a teacher and two children dead.
The shooter, described as "mentally ill," was later found dead, with officials saying he had shot himself.
In September 2021, a student dressed in black tactical clothing and helmet armed with a hunting rifle swept through Perm State University buildings killing six people, mostly women, and injuring two dozen others.
The gunman resisted arrest and was shot by law enforcement as he was apprehended and moved to a medical facility for treatment.
It was the second such attack that year after a 19-year-old former student shot dead nine people at his old school in Kazan in May.
Investigators said that the gunman suffered from a brain disorder, but was deemed fit to receive a license for the semi-automatic shotgun that he used.
On the day of that attack. Putin called for a review of gun control laws and the age to acquire hunting rifles was increased from 18 to 21 and medical checks were strengthened.
Authorities have blamed foreign influence for previous school shootings, saying young Russians have been exposed online and on television to similar attacks in the United States and elsewhere.
Other high-profile shooting cases have taken place in Russia's army, putting the issue of hazing in the spotlight in the country was military service is compulsory for men aged between 18 and 27.
In November 2020, a 20-year-old soldier killed three fellow servicemen at a military base near the city of Voronezh. In a similar attack in 2019, a young recruit shot dead eight servicemen, saying he faced bullying and harassment in the army.
