Three teachers killed in Bosnian school shooting

At least three teachers at a school in Bosnia and Herzegovina were killed during an assembly when a gunman, believed to be the school's former janitor, opened fire with an automatic rifle inside the building.

According to reports, the shooting occurred at around 10:15 a.m. local time at the Sanski Most high school in northwestern Bosnia. Another person was seriously injured in the attack and taken to hospital.

According to local reports, the dead are school principal Nijaz Halilović, English teacher Gordana Midžan and Nisveta Kljunić. Police investigations are ongoing.

Regional television station N1 reported that the suspected perpetrator had a dispute with the school administration. He is said to have shot the director and other school employees before attempting to kill himself.

Further details were not immediately available. Bosnian schools are closed for the summer holidays, meaning there were no classes taking place at the time of the shooting.
