French intelligence fears Islamist ‘missile strike on airliner’ or 9/11-style attack

French security forces are bracing for the eventuality of civil unrest and fear there could be a missile strike on a passenger airliner or a September 11-style attack, according to sources close to French intelligence.

“Airlines have been warned of a possible attack on a plane with an anti-tank missile,” a source told The Telegraph. “But pilots are unsure how to take evasive action.”
