A tray of food left by medics lies on the floor inside a field hospital, after what activists said were air and missile strikes in the Douma neighborhood of Damascus, Syria December 13, 2015. Douma in Syria, an area controlled by rebels fighting to topple President Bashar al-Assad, has been shelled continuously for the past three years. The injured are taken to basements and shelters transformed into field hospitals run by medical staff who have stayed in the battered neighbourhood of Damascus.
