Witnesses recount fleeing from Boko Haram fighters

Human rights group Amnesty International has released satellite images showing the scale of last week's attack on two Nigerian towns by Boko Haram fighters. Before and after images of two neighbouring towns, Baga and Doro Gowon in northern Nigeria taken on January 2 and 7, show the devastating effect of the attacks which left more than 3,700 structures damaged or completely destroyed. Those who fled the towns during the attacks have recounted how they escaped. Ahmed Idris reports from Abuja.
