Suspected bomb threats prompted security searches of seven aircraft across Europe on Tuesday, according to the BBC. Bulgaria confirmed that alerts were directed at flights arriving from Bergamo and Dublin, The Guardian reported.
Reuters reported that the threats caused disruption to air travel in several parts of the continent. The BBC said seven planes were searched following the suspected threats.
The alerts came from more than one country, based on the outlets' accounts. Bulgaria's confirmation, as reported by The Guardian, covered flights departing from Bergamo and Dublin, while the BBC's figure of seven searched aircraft indicates the response extended beyond a single airport or carrier.
The reports did not specify how many flights were delayed or cancelled, or whether anything suspicious was found during the searches. No further details on the origin of the threats were available in the material reviewed.
Authorities have not publicly linked the alerts to any group or individual, according to the reporting.
What to watch next: whether investigators identify a source for the threats and whether European airports and carriers adjust security procedures in response.
