Paris airports have tightened security since November attacks

French authorities have tightened security at Paris airports since last year's attacks in the capital, with thousands of border police officers, customs personnel, soldiers and private guards patrolling daily in the three airports serving the capital.

In addition to thousands of police, army and customs members, some 5,000 security guards working for private contractors are assigned to the Roissy-Charles-de-Gaulle, Orly and Le Bourget airports, according to Paris Aeroport, the authority in charge.
