School shooting leaves three dead as machine gun-wielding ‘janitor’ goes on rampage before trying to kill himself ‘after row with management’ in Bosnia

A gunman has left three people dead after rampaging through a school in Bosnia with an automatic weapon, according to local reports.

Three employees of a high school in the western town of Sanski Most were killed when a man, who is believed to have been a janitor at the school, opened fire at around 10.15am, police said.

The attacker turned the gun on himself, with cops saying ‘he tried to commit suicide and was gravely injured.’

The gunman was rushed for emergency treatment at a hospital in a neighbouring town, where he is said to be in a serious condition. 

Local media, citing witnesses, said the suspect had a history of disagreements with the management and had been under disciplinary proceedings when he sought out specific people and shot them in the bloody attack.

The victims have been identified by police as the school’s principal, a secretary and a teacher.

A number of staff members are gathered at the site in a ‘state of shock’ after they reportedly witnessed the bloody attack. 

Police and emergency services are on the scene and an investigation is underway

Bosnian schools are closed for the summer holiday, which means no classes were being held at the time of the shooting.

Sanski Most is about 180 miles (300km) northwest of Bosnia’s capital, Sarajevo. 

Mass shootings are comparatively rare in the Western Balkans which is awash with weapons that remained in private hands from wars in the 1990s.

In July, a war veteran in neighbouring Croatia shot five people including his mother in a nursing home and wounded six others.
