Sudan’s war was largely hidden from outside view until I managed to travel across the country last April, along with New York Times reporter Declan Walsh. Access had been virtually impossible on both sides of the conflict and I was the first photojournalist from an American news organization to reach the shattered capital, Khartoum, during the conflict, The work laid bare the ravages of a ruinous civil war. Up to 150,000 people had died and famine was closing in. I photographed silent streets strewn with corpses and hospitals packed with maimed and wounded soldiers.The work conveys not only the tragedy of war, but also the urgency of a humanitarian crisis that, by most reckonings, was ballooning into the biggest on the planet. Travelling to Chad, I found a sea of Sudanese refugees huddled in miserable desert camps. At a border crossing, I photographed a mother and her four children as they crossed from Sudan on a cart, the woman’s anxious face was a picture of her country’s suffering.
