Croatia: what’s behind the bomb threats?

The country is helpless in the face of these attacks, Telegram laments:

“It’s a particularly sensitive time for schools, because the final big exams are underway. … Missing lessons because of bomb threats is becoming increasingly problematic. … And it is also slicing into working hours, and, at shopping centres, profits. Not to mention the extra work for the police and bomb difusal units. The sheer number of bomb threats indicates that we are not simply dealing with teenagers trying to avoid exams here. If this is a hybrid war, then Croatia is losing it right now. Big time.”
