Americans marked one month since the Sept. 11 terrorist attacks, as U.S. military forces pressed ahead with bombing raids on targets in Afghanistan, preparing for ground operations meant to root out its Taliban rulers and Osama bin Laden's terrorist network.
Today, President Bush drew comparisons between the war on terrorism and World War II during a memorial service at the Pentagon in Arlington, Va.
"As Americans did 60 years ago, we have entered a struggle of uncertain duration," Bush said during the service. "But now, as then, we can be certain of the outcome, because we have a number of decisive assets.
"We have a unified country," Bush said. "We have the patience to fight and win on many fronts: blocking terrorist plans, seizing their funds, arresting their networks, disrupting their communications, opposing their sponsors. The president added that America has "one more great asset in this cause: the brave men and women of the United States military."
But hours after the service, Americans received a chilling reminder of the struggles likely to be facing them, as the FBI issued a new warning that new terrorist strikes may be imminent.
"Certain information, while not specific as to target, gives the government reason to believe that there may be additional terrorist attacks within the United States and against U.S. interests overseas over the next several days," the FBI said in a release. See Story

ABCNEWS has learned that U.S. special operations forces, on the ground in Afghanistan with some opposition groups, are helping to determine targets for American airstrikes — a new development Defense Secretary Donald Rumsfeld seemed to confirm today, saying "the United States is in communication with people on the ground in terms of gathering information as to military targets."
Targets that were hit earlier in the campaign have been struck again, including missile installations that survived the first round of bombings. But the focus on troop positions marked a major shift from bombardments earlier this week, when the primary targets were airports and air defenses.
The southern Afghan city of Kandahar, where the country's ruling Taliban militia has its headquarters, was hit again, and the capital of Kabul was subjected to its first daylight raids since the bombing campaign began on Sunday.
Refugees fleeing the bombing said most of the Taliban militia had moved out of the city, and headed for the border with Pakistan to prepare for a possible invasion.
The Pentagon released its first images of the war taken from gun cameras, showing an anti-aircraft target igniting after being struck. U.S. missiles. Bombs also seemed to target Taliban compounds, a military academy and troop positions around the capital, according to witnesses.
