FRANCE-GERMANY-SPAIN-AVIATION-ACCIDENT

Employees of Barcelona's El Prat airport hold a wreath of flowers as they observe a minute of silence at noon to honour the victims of the crash of an Airbus A320, in El Prat de Llobregat, south of Barcelona on March 25, 2015. An Airbus A320 operated by Lufthansa's Germanwings budget airline coming from Barcelona and heading to Dusseldorf crashed on March 24, 2015 in a remote area of the French Alps, killing all 150 people on board. Spain declared three days of mourning and King Felipe VI cut short his first state visit to France on March 24 just minutes after it began when he heard news of the tragedy.
