Policemen check luggage and passengers at Paris Charles de Gaulle’s international airport, on December 22, 2011, in Roissy following the government’s decision to deploy police to the airport to ensure a strike by security workers does not hamper holiday travel. The strike by workers demanding wage increases continued for a seventh day, but has so far had a limited impact on international flights, with only some delays reported.
