Montenegro declares December 23 as Day of Mourning over tragic event at Zagreb school

"We send our condolences to the family and friends of the injured child and pray for the speedy recovery of the injured. Our thoughts are with our neighbours," Spajic wrote on X.

In the horrific crime that shook Croatia and the region on Friday, a seven-year-old child was killed, and several children and a teacher were seriously injured when a 19-year-old attacker armed with a knife entered an elementary school in the suburbs of Zagreb. Among the injured was the attacker who tried to commit suicide, in which he was prevented by the police, after which he was arrested, Vijesti reported.
