Amnesty Images Show "Boko Haram Destruction" in Nigeria Human rights group Amnesty International says satellite images of Nigerian towns attacked by Boko Haram show widespread destruction and suggest a high death toll. The images show some 3,700 structures damaged or destroyed in Baga and Doron Baga this month. Nigeria's government has disputed reports that as many as 2,000 were killed, putting the toll at just 150. Amnesty cited witnesses saying that militants had killed indiscriminately. There has been a surge in violence linked to Boko Haram. In the past week there have been several attacks, including those by suspected child suicide bombers. Nigeria is to hold elections next month, amid growing doubts whether they can successfully go ahead in all parts of the country. BBC
