Zubeda Bi, Bhopal 2002. An estimated 20,000 people have died and tens of thousands have lived with debilitating illnesses since the gas leak. A week after this picture was taken in January 2002, Zubeda Bi died. She lost all her relatives in the disaster and lived in an out-building of someone's house in the Chola colony, where she was affectionately known as "Amma" (mother). Among those who looked after Amma were Asma and her niece, Raisa. Before she died, Zubeda Bi recalled the night of the gas leak to a representative of the Sambhavna clinic: "We couldn't see anything and were coughing. My grandson was one year old then. I put him on my chest to protect him as much as possible. But his face swelled to twice its size, his eyes were puffed tight. My eyes were so swollen that I couldn't see out of them. About an hour after I first felt the gas, we left the house. The streets were full of corpses. The skins of people were full of blisters. Nobody could be recognised."
