On 10 June 2025, a mass shooting occurred at BORG Dreierschützengasse, an upper secondary school in Graz, Styria, Austria. Oral Matura examinations were being held, and reporting stated that approximately 350 to 400 people were inside the building at the time.
Investigative reconstructions reported that the perpetrator entered the school at around 09:43 CEST. He went to a restroom on the third floor and armed himself with weapons carried into the building in a backpack. Reporting also described him wearing shooting glasses and a headset, and carrying a weapons belt and a hunting knife.
The first shots were reported at 09:57, fired in a classroom on the second floor. The perpetrator then moved back to the third floor and opened fire in another classroom after shooting at a lock to gain entry. The total duration of the shooting was described as about seven minutes, with approximately 40 gunshots fired.
At 10:07, the perpetrator returned to a school lavatory and died by suicide inside a toilet cubicle. Police stated that the scene was secured shortly after emergency calls, with large-scale deployment including special units. Major reporting described hundreds of officers responding and the school being evacuated quickly once security forces arrived.
Ten victims were killed in the attack. Reporting described the dead as including nine students and one teacher, with the teacher dying later at a hospital. The perpetrator was also among the deceased, bringing the total number of deaths to eleven including him. Sources described the students who were killed as being in their mid-teens, and reporting noted at least one non-Austrian national among those killed.
Injury reporting varied by source and by whether counts referred only to gunshot wounds or to total hospital-treated casualties. Wikipedia’s summary reports more than 30 treated injuries overall, with 11 from gunfire, while major early coverage reported 11–12 wounded.
Following the shooting, police searched the residence associated with the perpetrator and found a farewell note and a video message. Officials cited in reporting stated that the note functioned as a goodbye message and did not provide a clear reason for the attack. Police also recovered a non-functional pipe bomb and materials described as showing that a bombing plan had been considered and later abandoned. Public officials stated in the immediate aftermath that motive claims were speculative while investigative work continued.
