The series is not limited to air traffic. Irish and British media outlets, including Sky News, as well as French media such as TF1, have also received bomb alerts.
These false alerts, which are difficult to attribute, have the effect of mobilizing security services and sowing fear at low cost, experts stress.
This procedure comes as dozens of commercial flights have been the subject of bomb alerts in Europe since the beginning of the week.
Investigators are therefore seeking to identify the senders of these messages and to determine whether they have a link with outside actors.
The day before, Thursday, an Aer Lingus plane had been diverted to Évreux after a bomb alert.
Each report leads to checks, sometimes a diversion, and the intervention of bomb disposal teams, even though the messages prove unfounded.
