On Friday, Serbian police arrested a suspected gunman believed to have killed eight people and injured 14 in a village near Belgrade, marking the second mass shooting in the country this week. The suspect, identified as U.B. and born in 2002, was apprehended near the city of Kragujevac. The shooting took place in Dubona, a village close to Mladenovac, and was reportedly carried out by the suspect, who left an altercation at a school yard on Thursday before returning with an assault rifle and a handgun. On Wednesday, a 13-year-old boy killed nine and injured seven at a school in Belgrade before surrendering to the authorities. Serbia is currently in three days of official mourning following the incidents. The government has also introduced a two-year ban on issuing new gun permits and is reviewing existing permits, as well as the storage of firearms. Gun culture is prevalent in Serbia and the wider Balkan region, which has one of the highest numbers of guns per capita in Europe.
