Before being taken down, a YouTube channel named “Robin W” hosted at least two videos. One video, approximately 10 minutes long and filmed on a mobile phone, showcased various weapons, ammunition, and loaded magazines. The inscriptions “Kill Donald Trump,” “kill Trump now,” “Israel must fall,” and “Burn Israel” were written on the magazines. One weapon featured the words “Nuke India.” Other writings included “Where is your God?” and “for the children.” Names of previous school shooters were also scribbled on a magazine, with some messages in Cyrillic script. The video also depicted the person holding a smaller firearm and stating, “This one is for me. In case I need it.”

The attack took place at the Annunciation Church, which also houses a grammar school. An official from the hospital stated that among the 17 injured, 14 were children, with seven in serious condition.

Minneapolis Police Chief Brian O’Hara reported that the gunman, believed to be around 20 years old, was carrying a rifle, a shotgun, and a pistol. Police also indicated that the suspect did not have a significant criminal history. Addressing a press conference, the police chief said the shooter approached the school outside the building during Mass and began firing through the church windows with a rifle. He added that the shots were fired at children who were sitting in prayer. The suspect fired shots at children and worshippers inside the building.

U.S. President Donald Trump posted on Truth Social that he had been informed about the “tragic shooting” and that the White House was monitoring the situation. Trump wrote, “The White House will keep a close watch on this horrific situation. Please join me in praying for all involved!” Minneapolis Mayor Jacob Frey was also present at the press conference with the police chief. The mayor stated that children should be playing on playgrounds. They should have the freedom to go to school or church in peace, without fear or the risk of violence.

Minnesota Governor Tim Walz also wrote on social media that he had been briefed on the shooting and that he was praying for the children and teachers whose first week of school had been impacted by this horrific act of violence.

FBI Director Kash Patel stated that agents from the agency were on the scene. Patel wrote on X, “We are aware of reports of a shooting at a Catholic school in Minnesota. FBI agents are on the scene, and we ask everyone to keep potential victims, civilians or law enforcement in harms way in your prayers. The FBI will provide updates as more information becomes available.”

The incident occurred at the BORG Dreierschützengasse high school. Emergency services, including special Cobra units and a helicopter, were swiftly deployed to the scene after authorities received a call at 10 am local time. Police confirmed that the school was evacuated and everyone was moved to a safe location. Authorities later declared the situation as ‘secured,’ indicating that the immediate danger had passed.
