There's been little information in Haiti about a man pulled from the rubble of a store Tuesday.
The 35-year-old says he had been trapped since the earthquake, more than two weeks ago. U.S. soldiers have treated him for a broken leg and severe dehydration.
Meanwhile, the international aid effort in Haiti remains hampered by an overloaded airport and crippled seaport.
European officials say there's a seven-day backlog of some 800 to 1,000 aid flights still awaiting permission to land. U.N. spokeswoman Elisabeth Byrs says "trucks are needed," especially small trucks because "the streets are extremely congested."
U.N. relief coordinator John Holmes estimates that 2 million people need food, but only 500,000 have received some so far.
Brazilian troops fired pepper spray on a jostling, rowdy crowd of earthquake survivors waiting for food.
The medical picture has improved, but remains critical.
