UMM QASR, Iraq April 11 -- Every sunrise brings out a new wave of the sick and the desperate, but this was the worst sight yet: a crying woman, a man holding a child and the unmistakable smell of kerosene. Thirty minutes before, the child was a thirsty 2-year-old who saw a bright pink cup filled with liquid outside his front door. Now, limp in his father's arms, he was the morning's first example of the medical chaos that has descended on liberated Iraq.
