At least eight people have been killed and several others injured in an attack at a school in Graz, Austria, according to local media reports on Tuesday.

Austrian tabloid Kronen Zeitung reported the fatalities, while public broadcaster ORF, citing police sources, said that a number of people — including both students and teachers — sustained serious injuries.

Police confirmed that an operation was ongoing on Dreierschuetzengasse, a street where a secondary school is located, though they declined to provide further details.

According to ORF, authorities are currently evacuating the school building.

Still to be confirmed, reports say that the suspected attacker is believed to have taken his own life in a school restroom.
