Serbia in shock after 13-year-old kills 9 in school shooting

A 13-year-old boy opened fire at a school in Belgrade, Serbia, killing at least eight children and a security guard. The boy had two guns and four Molotov cocktails in his possession. The suspect's parents were arrested, and the father had previously taken his son to a shooting range. The boy will not be held criminally responsible as he has not reached the age of 14. The incident has sparked a national conversation about Serbia's gun laws and age of criminal responsibility. Three days of mourning have been declared in Serbia.
