Fear is the biggest enemy, says veteran war correspondent

"Skeleton children, exhausted by starvation, roamed around like ghosts. Some would just collapse, dying of hunger under the scorching sun. I got down on my belly on the ground to get some shots when my Ethiopian driver started shouting at me to get up fast, pointing to the sky. Huge buzzards, with legs as big as my arm and talons like scythes were circling low in the sky. The driver waved his arms in the air, desperately trying to chase them off. 'If they see someone on the ground they'll attack and tear him up with their beaks and claws. They think he's dead. They might even pick up smaller bodies and take them back to their nests to feed their young,' he told me. I took a couple of quick shots of a subject that confirmed in the most brutal manner the adage that one man's death is another man's life and got out of there as fast as I could."
