Two passengers with names linked to Islamic terrorism were on board the Air France flight that crashed in the Atlantic Ocean, killing all 228 on board, it has emerged.
French secret servicemen established the connection while working through the list of those who boarded the doomed Airbus in Rio de Janeiro, Brazil, on May 31.
Agents are now trying to establish dates of birth for the two dead passengers, and family connections.
There is a possibility that the name similarities are simply a "macabre coincidence," the source added, but the revelation is still being "taken very seriously."
A source working for the French security services told Paris weekly L’Express that the link was "highly significant."
