(ANSA-AFP) - BELGRADE, AUG 21 - Three employees were shot dead Wednesday at a high school in northwest Bosnia by a co-worker who then tried to kill himself, police said. The shooting occurred around 10:00 am (0800 GMT) in Sanski Most as teachers met to prepare the upcoming school year and no students were present, local media reported. The violence comes after high profile mass shootings in other Balkan nations in recent years, including back-to-back attacks that rocked Serbia in 2023. (ANSA-AFP).
