The aircraft carrier USS Abraham Lincoln will withdraw from Indonesia's tsunami-battered Sumatra island on Friday in the single biggest draw down of the American military aid effort since the Dec. 26 disaster. The ship, with 5,300 sailors and Marines aboard, "is moving out of Indonesian waters," said U.S. Navy spokesman Cmdr. Mark McDonald. A U.S. Embassy statement said the Abraham Lincoln will depart the area on Friday. It is expected to head for Singapore.
