Austria school shooting latest: Death toll rises to 11 as police reveal gunman to be a former pupil

Buses, trams and trains in Austria will stop for a minute’s silence at 10am (9am BST) today.

According to Kronen Zeitung, all 900 vehicles will remain stationary for one minute to the victims.

If a vehicle is between stops, it will continue to the next stop.

Investigators found a farewell letter and a non-functional pipe bomb when they searched the home of the gunman who killed 10 people and injured more in a school shooting yesterday.

The 21-year-old Austrian man lived near Graz and was a former student at the BORG Dreierschutzengasse high school, in Austria's second-biggest city, who had not completed his studies.

Police have said that he used two weapons, a shotgun and a handgun, which he appeared to have owned legally.

Investigators said the note did not reveal the motive for the attack.

Franz Ruf, director general of public security, said investigations into the motive were moving swiftly.

"We don't want to speculate at this point," he told Austrian broadcasterORF on Tuesday night.

The gunman who opened fire in a school in Graz, killing 10 people before turning the gun on himself, has been identified as a 21-year-old Austrian national.

Police said they believed the shooter, who was found dead in a bathroom, had been operating alone when he entered the school with two guns and opened fire.

The gunman, who lived near Graz, was a former student of the BORG school and did not complete his education at the institution. Police did not release his name or specify when the man left the school or at what age.

Director General for Public Security, Franz Ruf, told ORF the suspect had left behind a farewell letter, both in analogue and digital form, in which he said goodbye to his parents but gave no indication of a motive.

Mr Ruf said the perpetrator owned a shotgun and a handgun, and "he used both weapons", which were found at the crime scene.

Special forces were among those sent to the BORG Dreierschützengasse high school in Graz yesterday around 10am local time after a 21-year-old gunman opened fire, killing 10 people.

More than 300 police officers were sent to the school, which was evacuated, the authorities said. Footage from the scene showed students filing out quickly past armed officers.

Police said security was restored in 17 minutes. Metin Özden was in his kebab restaurant near the school when he first heard police cars sped by, and then a police helicopter above.

He told the Krone newspaper: “I knew something bad had happened. … I’ve never seen so many emergency services in my entire life.”

Austria will observe a nationwide minute's silence today at 10am local time in memory of the 10 people killed in one of the worst mass shootings in the country's recent history.

Austrian chancellor Christian Stocker said there would be three days of national mourning, with the Austrian flag lowered to half-staff.

The shooter opened fire at a school in Graz yesterday, fatally wounding 10 people before taking his own life, authorities said. Authorities earlier said another 12 people were wounded.

The 21-year-old pupil who shot dead 10 people at a secondary school in Austria's second city, Graz, on Tuesday was armed with both a shotgun and a pistol.

Director General of Public Security Franz Ruf told state broadcaster ORF that victims were found outside and inside the school on various floors.

Police said they believed the 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.

The Salzburger Nachrichten newspaper said in an unconfirmed report that the suspect had opened fire on pupils in two classrooms, one of which had once been his own. It said he had been a victim of bullying.

Hundreds of people poured onto the streets of Graz in Austria to hold a vigil for the 10 victims of a school shooting.

Authorities said the gunman, a 21-year-old Austrian national, opened fire at the BORG school in Graz, before turning the gun on himself."It shocked me a lot like everybody else," local resident Elisabeth Schuster was quoted by Euro News as saying.

"I’m with them, feel for them. And I hope that together we can find a way, so that something like this never happens again," she added, referring to the victims.

Austrian chancellor Christian Stocker, along with vice chancellor Andreas Babler and foreign minister Beate Meinl-Reisinger attended the mass at Graz Cathedral yesterday.

UN secretary-general Antonio Guterres is deeply shocked and saddened by the school shooting and strongly condemns "this senseless act of violence", his spokesperson said.

Mr Guterres extends his heartfelt condolences to the families of the victims, the people of Graz and the government of Austria.

He wishes a swift and full recovery to all those injured, spokesperson Stephane Dujarric added.
