A shooting in Cetinje, Montenegro, led by 45-year-old Aco Martinovic, resulted in twelve fatalities, including two children aged 11 and 7, and four injuries. The assailant reportedly opened fire in a bar linked to the Vuletić family and later shot himself. Preliminary reports suggest personal animosity as the motive behind the attack. Montenegro’s government is expected to announce a three-day mourning period for the victims.
