Nina Berman won a prize in the 2007 World Press Photo contest for this heartbreaking photo of a badly wounded Iraqi war veteran and his childhood sweetheart on their wedding day. Their story is here. "One arm was a stump and his remaining hand had only two fingers. Later, his big toe was grafted on in place of a thumb. One eye was blind and milky, as if melted, and his ears had been burnt away. The top of his skull had been removed and inserted by doctors into the fatty tissue inside his torso to keep it viable and moist for future use." (thx, ayush)
Update: Here are some more of the couple's wedding photos and more photos of Iraqi vets from Berman here and here.
