At the foot of the hills in Thangkali in south-eastern Bangladesh, 50-year-old Aziza rests her head on the shoulder of one of her teenage sons. She is one of hundreds of people sitting in the mud by the roadside. “I had tarpaulins back at home but when the fighting started, I dropped them and ran,” says Aziza. She recounts how her husband was shot when conflict erupted in their village in Rakhine state. She then reaches into her small bag and removes a photograph. She points to the man in the middle of the picture.
