Chad Sahel Hunger

FILE - In this Friday, April 20, 2012 file photo, a young girl carries an empty container as she walks across the sands to fill it from a well in Barrah, a desert village in the Sahel belt of Chad. Mothers with hungry and malnourished children are flocking to feeding sites and clinics in the Chadian desert by any means they can and where it is sometimes too late to save their babies' lives, with health and U.N. officials warning that more children will die if the international humanitarian assistance is not increased.
