A former student killed 10 people and himself at a secondary school in Austria's second city, Graz, on Tuesday in the worst school shooting in Austria's modern history.
Interior Minister Gerhard Karner said six of those killed at the school were female and three were male. Graz hospital later confirmed the death of a 10th person.
Karner said another dozen people had been injured but gave no further details about the victims. Austrian media said most were students.
Police said they believed the 21-year-old Austrian shooter, who was found dead in a bathroom, had been operating alone when he entered the school with two guns and opened fire. His motive remained unclear.
Chancellor Christian Stocker called the shooting a "dark day in the history of our country".
"There are no words for the pain and grief that we all — all of Austria — are feeling right now."
Stocker travelled to Graz where, at a press conference alongside officials including Karner, he announced three days of national mourning. A minute's silence was set for 10am local time on Wednesday.
The Kronen-Zeitung newspaper said police had found a farewell note from the shooter at his home. The paper did not say what it contained and police were not immediately available to comment.
More than 300 police were called in after shots were heard around 10am at the school, for pupils of 15 and above. Ambulances also arrived within minutes as the premises were cordoned off.

Police said investigations into a motive were continuing.
Julia Ebner, an extremism expert at the Institute for Strategic Dialogue think-tank, said the incident appeared to be the worst school shooting in Austria's post-war history.
Foreign leaders including German Chancellor Friedrich Merz expressed shock.
Austria has one of the most heavily armed civilian populations in Europe, with an estimated 30 firearms per 100 people, according to the Small Arms Survey, an independent research project.
Four people were killed and 22 injured when a convicted jihadist went on a shooting spree in the centre of Vienna in 2020. In November 1997, a 36-year-old mechanic shot dead six people in the town of Mauterndorf before killing himself.
