U.S. and U.N. boost Haiti aid security as food drops in

PORT-AU-PRINCE (Reuters) - U.S. troops protected aid handouts and the United Nations sought extra peacekeepers in earthquake-shattered Haiti on Monday as marauding looters emptied wrecked shops and desperate survivors began to receive medical care and air-dropped food.

Hundreds of scavengers and looters swarmed over damaged stores in Port-au-Prince, seizing goods and fighting among themselves, but some signs of normality returned as street vendors emerged with fruit and vegetables for sale. In the evening, gunfire could be heard in the wrecked capital city.
