PARIS, Jumada II 19, 1436, Apr 8, 2015, SPA -- French air traffic controllers went on strike Wednesday, prompting the cancellation of 40 percent of flights across France, AP reported. The powerful SNCTA union called the two-day strike in a quarrel over working and retirement conditions. France's main airline, Air France, said long-haul flights would not be affected, and guaranteed some 60 percent of medium-haul flights from and to Paris' main airport, Charles de Gaulle. --SPA 12:08 LOCAL TIME 09:08 GMT www.spa.gov.sa/w
