Amnesty International said the detailed images of Baga and Doron Baga, taken before and after the attack earlier this month, show that more than 3,700 structures were damaged or completely destroyed. The images were taken Jan. 2 and Jan. 7, Amnesty International said. Boko Haram fighters seized a military base in Baga on Jan. 3 and, according to witnesses, killed hundreds civilians in the ensuing days. Daniel Eyre, Nigeria researcher for the human rights group, said in a statement that the assault on the two towns was the largest and most destructive of all the Boko Haram assaults analyzed by Amnesty International.
