Ten people were killed in the attack at the secondary school on Tuesday - the deadliest in the country's recent history.

Students were sitting in their classrooms at a secondary school in Graz when a 21-year-old Austrian man shot dead nine people, before killing himself.

But that all changed at about 10:00 on Tuesday when a former student ran amok at a secondary school in the Dreierschützengasse, close to the main station in Austria's second largest city.

The incident took place at Dreierschützengasse secondary school in the north-west of the city.

Primary pupil numbers are decreasing, though, as birth rates fall, and staffing issues have been felt most acutely in secondary schools - particularly in specialist subjects like maths, science and languages.
