Two Air France flights headed for Paris have been diverted following suspected bomb threats, it was reported.
One flight, from Washington D.C. to Paris, was diverted to Halifax, Nova Scotia.
Another, from Los Angeles to the French capital, was diverted to Salt Lake City, according to CNN.
The security alerts come just days after Paris was targeted by ISIS terrorists.
129 people were killed in a series of co-ordinated bomb and gun attacks on Friday night.
With 99 of the 352 wounded critically ill, the death toll is expected to rise.
