UPDATE | 🇪🇺 More than 50 flights across Europe have been affected by bomb threats this week.
At least 18 flights were affected on Friday alone, including nine arriving at or departing from Prague Airport.
Several aircraft have been diverted, others searched after landing, and fighter jets have been scrambled to escort passenger flights. So far, security inspections have found no explosives.
The disruption has also extended beyond aviation. Media organisations in Ireland and the UK received separate threats on Friday, prompting evacuations and police investigations.
The scale is unusual, even if the affected flights represent a tiny fraction of European air traffic.
A relatively simple threat can trigger expensive security procedures across multiple countries.
