Mahamat Djouma is one of the millions displaced by the civil war in Sudan. He is part of an especially vulnerable group — unaccompanied minors. Here is his story.

Sudan's civil war has displaced 10 million citizens. Here are profiles of two young people from the most vulnerable groups: an unaccompanied minor caring for twin brothers, a woman who was raped.

In one refugee settlement in Chad, estimates are that 97% of the Sudanese residents are women and children. Here's how four women there are mourning the loss of a partner and struggling to get by.

It is the world's largest displacement crisis: 13 million people have fled their homes in war-torn Sudan. In neighboring Chad, both refugees and locals cope with this extraordinary upheaval.

Hundreds of thousands of Sudanese, fleeing civil war, arrive in Chad hoping for safety and food. What they find, however, is there just isn't much food. Many refugees are suffering from malnutrition.

The refugees escaping the civil war in Sudan recount the violence which took the lives of many men and boys. That violence, they say, was directed towards those of particular tribes and skin colors.

Tens of thousands of Sudanese have fled civil war and are crossing into Chad for safety. At the border, we hear from people — mostly women — on what they've seen and experienced that forced them to leave.

A team of independent famine experts, working under the U.N. umbrella, believe Sudan is experiencing famine. But issuing a declaration — which could bring in more aid — turns out to be complicated.

The government of Sudan has not made an official declaration of famine and denies that famine exists. Aid groups are concerned that without a declaration, international resources won't be mobilized.

The virus has been confined to certain areas of the Amazon but is moving into new turf as climate change enables the insects that spread it to spread out. Here's what we know.
