In Somalia, a lethal mix of drought, poverty, war and political instability has led to widespread famine. Tens of thousands have died, and half a million children are on the brink of starvation. Refugees — mostly women and children — have flooded into the Dadaab refugee complex in northeastern Kenya, overwhelming aid workers and exhausting supplies at the world’s largest refugee camp. But it’s the lucky ones that make it to Dadaab. Al Shabab Islamist militia, who control much of southern Somalia, have made it difficult for drought victims to reach the border. Over 100,000 have come to the capital, Mogadishu, where new camps for the internally displaced are sprouting up amid the crumbling, bullet-riddled ruins of the city.
