Air France says false alert after Paris-bound plane diverted to Montreal due to threat
"After a full security search, false alert confirmed by local authorities following an anonymous threat," the carrier said in its Twitter account.
The plane had taken off for Paris again.
Security officials worldwide have been on high alert since Islamic State militants claimed responsibility for attacks in Paris last month that killed 130 people.
