70 Paris Airport Workers Fired in Dec Over Suspected Extremist Links

LATEST: Investigators Looking at Paris Airport Workers After EgyptAir Crash

The U.S. is helping out in the crash investigation of EgyptAir Flight 804 that went down early Thursday in the Mediterranean Sea with 66 people on board. 

Catherine Herridge reported that the U.S. is sharing all relevant intelligence with French and Egyptian investigators who have the lead.

This typically includes signals intelligence, as well as threat data held by the National Counterterrorism Intelligence Center, the nation's hub for threat analysis.

Once the passenger manifest is shared with the U.S., the names will be run against watch lists to determine whether anyone had ties to known terrorist groups.

House Homeland Security Committee Chairman Michael McCaul (R-TX), who has been briefed, says this incident may be similar to the downing of the Russian passenger jet last October by ISIS.

An intense search continues in the Mediterranean Sea off Greece for wreckage of the Airbus A320. There were conflicting reports throughout the day as to if any debris from the plane was spotted by search crews.

Ahmed Adel, Vice President of EgyptAir, told CNN the debris found Thursday was not from Flight 804.

No explosion was detected by U.S. infrared satellites in the vicinity of the EgyptAir crash in the eastern Mediterranean, multiple U.S. officials told Fox News.
