Croatia is under a wave of fake bomb threats - and the wave isn't stopping. Over the past few days, hundreds of reports have rocked Zagreb, Split, Rijeka and Dubrovnik. Primary and secondary schools, newsrooms, government institutions, shopping centers, even Split airport - everything has received a threat by email. The result: evacuations, panicked parents, children in the street instead of in classrooms.

The number is staggering - over 500 false reports in just five days. The Croatian police are on the case, but they've confirmed that the threats are coming from foreign servers, through foreign domains. The investigation is being run together with European partners. So far: not a single perpetrator identified.

Interior Minister Davor Božinović called this "hybrid warfare." Strong wording - but also an admission that this isn't a routine teenage prank. Croatian police uncovered that part of the threats come from the same sources, that there is a pattern, that someone with resources and intent is behind all of it.

Psychologists are already warning: children going through repeated false alarms develop a lasting fear - sleep problems, concentration issues, a sense that the world is more dangerous than it is. "Hybrid" or not, the consequences are very real.

The Balkans remember destabilization campaigns. This one doesn't look random - but who's sending them, and why right now, is still the subject of an investigation.
