Police have cordoned off a school compound in Sanski Most, a town in northwest Bosnia-Herzegovina, after an employee shot dead three of his colleagues on August 21. An investigation is under way to ascertain the motives of the shooter who used an automatic rifle. After the attack, he apparently tried to kill himself and was hospitalized with a gunshot wound to his chest. Although Bosnian schoolchildren are still on vacation, police say that some pupils were retaking exams in the building when the gun attack took place.
