As I stood there, distressed, ashamed, helpless, I heard a woman shouting in an unearthly voice. Everyone looked in the direction of her cry and a couple of GPU men started running towards her. The woman, her hair streaming, held a flaming sheaf of grain in her hands. Before anyone could reach her, she had tossed the burning sheaf on to the thatched roof of the house, which burst into flame instantaneously.
