Inside the main school building three children lay dead. One was Zin Nwe Phyo. Another was seven-year-old Su Yati Hlaing - she and her older sister were being brought up by their grandmother. Their parents, like so many in this region, had moved to Thailand to seek work. Others were horribly injured, some missing limbs. Among them was Phone Tay Za, also seven years old, crying out in pain.
