Djibo, a dusty town in northern Burkina Faso, has become a byword for suffering in this impoverished country's seven-year-old struggle with jihadism, which has forced an estimated 300,000 people to flee their homes. Among them is Boureima, head of a family of 43 people -- seven men, 13 women and 23 children. They abandoned their village of Gassalpalik, 70 kilometres (44 miles) from Djibo, eventually washing up in Yagma, a village about 30 kms north of the capital Ouagadougou.
