Fox News chief intelligence correspondent Catherine Herridge brought us the latest on the EgyptAir tragedy.

Russian and Egyptian officials say terrorism was the most likely cause of the disappearance of EgyptAir flight MS804, which went missing in the Mediterranean Sea while on its way from Paris to Cairo.

Herridge said French officials are exploring the possibility that Flight 804 was brought down in a similar fashion to the Russian passenger plane that was blown out of the sky over the Sinai Peninsula last year. 

Herridge said they're looking into the Charles de Gaulle Airport workers who would have had access to the Airbus before it departed.

Moscow has said that the flight in October was brought down by an explosive device and a local branch of ISIS claimed responsibility for planting it.

In December, 70 workers at Paris airports had their security passes revoked due to suspected links to extremist groups. 

Herridge said that a senior French intelligence official warned last week that ISIS may look to attack with package bombs, but he did not specify an air attack. 

Greek officials now say they've located debris that they believe is from the downed Airbus.

Herridge said officials are also looking at the passenger list to see if anyone onboard was on a watch list or had ties to terrorism. 

She said it's too early to say whether a bomb was placed on board the plane.
