"In Donetsk the sound of explosions is always there, in the background." writes AFP reporter Simon Valmary. "Heavy artillery, mortar fire, rockets: after nine months of fighting, residents of the town held by pro-Russian rebels can tell most types of blast apart…. But without knowing, most of the time, who is bombing whom. Civilians try their best to go about their daily lives in spite of these shells that can fall from anywhere, at any time, striking people dead on the sidewalk."
