WASHINGTON (Reuters) - The Pentagon on Wednesday raised the alert level at military bases, most of them domestic, ahead of the 10th anniversary commemorations of the September 11, 2001, attacks on Sunday.
"This is not in response to any particular threat but is a prudent and precautionary measure," said Pentagon spokesman George Little. The Pentagon said the move takes effect on Wednesday and will continue through Sunday.
Security officials are being especially vigilant as the 10th anniversary of the September 11 attacks approaches.
The State Department issued a "Worldwide Travel Alert," saying Americans traveling and living abroad should be aware of the continued threat posed by al Qaeda and its affiliates.
"As you all have seen, the 10th anniversary of 9/11 was mentioned in the documents seized at the Abbottabad compound," Little said.
"Now this does not suggest in any way, shape or form that we know about a specific or credible threat to the United States homeland surrounding the 10th anniversary."
