New satellite images and witness accounts have emerged of what Amnesty International calls the “catastrophic destruction” from a massacre in northern Nigeria. Hundreds are feared dead after Boko Haram militants attacked Baga and surrounding areas earlier this month. Before and after images taken of two adjacent towns show thousands of buildings damaged or destroyed. Amnesty says one town was completely “wiped off the map.” One witness who managed to flee told Amnesty: “I don’t know how many but there were bodies everywhere we looked.” The Nigerian military has claimed a toll as low as 150, but it could be as high as 2,000. Amnesty said: “Of all Boko Haram assaults analyzed by Amnesty International, this is the largest and most destructive yet — a deliberate attack on civilians whose homes, clinics and schools are now burnt out ruins.”
