For South Sudanese living in 'the bush,' a fight against hunger, disease, and violence

Bodies stuffed in wells. Houses burned down. Children playing on military hardware. And infants showing the skeletal outlines of severe hunger.

These are scenes from a remote part of South Sudan — Leer — where Doctors Without Borders has just begun feeding severely malnourished children about three months after the group's hospital was destroyed in violence that has been ripping apart the country since December.

One child brought to the clinic by a mother hoping for life-saving aid instead died the next day.

U.N. Secretary-General Ban Ki-moon says he visited South Sudan to "sound the alarm about the violence and the risk of catastrophic famine." Ban warned that if fighting continues, half of South Sudan's 12 million people will be displaced internally, refugees abroad, starving or dead by year's end.
