Lit candles are placed outside the Josef-Koenig-Gymnasium high school in Haltern am See, March, 24, 2015. Students and teachers at a small-town German high school broke out in tears when they realised that 16 classmates and two teachers were on board an ill-fated Germanwings airplane that crashed in France on Tuesday on a flight home to Duesseldorf. The text reads: ‘In silent sympathy.’ REUTERS/Kirsten Neumann
