What happened in Baga? Survivors relive attack
Scores of men, women and children were killed in the Nigerian towns of Baga and Doron Baga on 3 January when Boko Haram militants launched a fierce attack. The exact number of dead remains unknown, but claims vary from 150 to 2,000 people killed. Thousands more fled across Lake Chad. The BBC's West Africa correspondent Thomas Fessy met survivors at refugee camps in Chad in order to piece together a picture of what happened that day.
