Air France said Wednesday that two Paris-bound flights that had been diverted following anonymous threats have landed safely.
Air France said the flights were subjects of anonymous threats received after their respective take-offs and authorities subsequently noted the absence of credible evidence to the threats.
"Law enforcement personnel have conducted intensive security checks in accordance with protocol and have not located any evidence which would lend credibility to the threats," Todd Palmer, a special agent at the Salt Lake City division of the FBI said in a statement.
"In order to ensure the safety of the passengers, crew, and public, law enforcement officers will be working throughout the evening to further determine the credibility and genesis of the threats," he said.
Flight A5055 from Washington to Paris landed safely in Halifax, Nova Scotia, while flight A5065 from Los Angeles to Paris, landed safely in Salt Lake City, Air France said in a statement posted on its Twitter account.
Air France Flight 55 from Washington Dulles had 234 people aboard, and Flight 65 from Los Angeles had 473 aboard, Air France spokesperson Christophe Paumier said. Flight 55 was a Boeing 777 and Flight 65 was an Airbus 380.
The threat followed last week's deadly terrorist attacks claimed by Islamic State in Paris that prompted French President Francois Hollande to declare a state of emergency for three months and spurred other countries in Europe to a state of high alert.
A soccer match between Germany and the Netherlands was cancelled on Tuesday after a bomb threat.
Local authorities are now carrying out complete inspection of the aircraft, the passengers, and their luggage, Air France said.
