Two Air France flights en route to Paris from the United States were diverted on Tuesday following anonymous threats, and passengers and crew were safely removed, the airline and the Federal Aviation Administration said.

An Airbus A-380 that departed from Los Angeles landed in Salt Lake City, where passengers and crew were taken off the plane and escorted into the terminal, an FAA spokesman said.

A separate flight that left Dulles International Airport outside Washington, D.C., was diverted to Halifax International Airport in Nova Scotia, where passengers and crew disembarked.
