This famous, terrible and tender picture was taken by Magnum photographer Raghu Rai on the morning of December 3rd, 1984, after the night of horror in Bhopal when a huge cloud of poison gas 500 times more toxic than hydrogen cyanide spewed from a factory belonging to Union Carbide Corporation.
Thousands died in hideous ways. As the sun rose on streets full of corpses, Raghu found himself in a graveyard where a man was burying his young daughter. The father had covered the tiny body but then, unable to bear parting from her, brushed the earth away for one last look.
For the Bhopalis this picture has come to symbolise 30 years of unimaginable suffering, an injustice never righted, crimes unpunished, and a community that most of the world has forgotten.
