As the nation and the world marked the 10th anniversary of the Sept. 11 terrorist attacks, Associated Press journalists tracked down the most salient details of the day and captured the mood, from ground zero to Afghanistan.

Here's how the day unfolded, together with occasional flashbacks to AP reports distributed on Sept. 11, 2001, up until the moment Osama bin Laden was named as the chief suspect. The archival material was left as transmitted 10 years ago, including the original typos, as well as information from AP sources that later turned out to be incorrect.

Bin Laden was killed in Pakistan by U.S. special operations forces in May 2011.

Las Vegas firefighter Gregg Burns found new life for an American flag that he received in a parade this morning marking the 9/11 anniversary.

He stuck it to his helmet for a 108-story climb a couple of hours later up the Stratosphere casino tower on the Las Vegas Strip.

Around his neck, the 49-year-old wore the names of New York firefighters Thomas Gambino Jr. and Stephen E. Belson, who died in the collapse of the 110-story World Trade Center towers.

"Bottom line, this is for them," Burns said, as he and 290 others prepared to ascend the tallest building in Las Vegas, in memory of the firefighters and police officers who died climbing the twin towers decade ago.

"This is nothing like what those guys went through," Burns said. "People need to be reminded."

"How you doing? How you doing? You got a job and that's a great thing to be pursuing!"

She directed her rhymes at a man carrying a bundle of newspapers on his bicycle. The man looked straight ahead, but cracked a smile.

"I know it's Sept. 11, but it's also a great morning," said the rapper, who goes by The Artist Annisha. "We have to stay positive here."

Some, who were homeless, received free cookies and coffee.

Ron Blakley, the tall, goateed singer and steel guitar player, is an Evangelical Episcopalian preacher. Robert's _ which is usually filled with beer- and whiskey-drinking tourists and country fans _ becomes Blakley's church on Sunday mornings.

He quoted Scripture and talked about Sept. 11 between songs.

"We can't avoid the suffering that life brings," he said. "But good things can happen on a bad day."

He ended up helping with demolition at the World Trade Center site for six weeks.

World Trade Center collapses in terrorist attack; Washington hit by apparently coordinated attack

By JERRY SCHWARTZ

AP National Writer

In one of the most audacious attacks ever against the United States, terrorists hijacked two airliners and crashed them into the World Trade Center in a coordinated series of blows Tuesday that brought down the twin 110-story towers. A plane also slammed into the Pentagon, bringing the seat of government itself under attack.

Thousands could be dead or injured, a high-ranking city police official said, speaking on condition of anonymity.

Of the top Twitter trends at the moment, only one _ the hashtag GodBlessAmerica _ has anything to do with 9/11. Other trends include "Happy Grandparents Day" (which happens to be today) and "Today is 9-10-11" (which, of course, it isn't).

Therefore, we will not fear, even though the earth be removed, and though the mountains be carried into the midst of the sea.

Though its waters roar and be troubled, though the mountains shake with its swelling, there's a river whose streams shall make glad the City of God, the holy place of the Tabernacle of the Most High.

God is in the midst of her.

She shall not be moved.

God shall help her just at the break of dawn.

The nations raged, the kingdoms were moved.

He uttered his voice.

The earth melted.

The Lord of Hosts is with us.

The God of Jacob is our refuge.

Come behold the works of the Lord who has made desolations in the Earth.

He makes wars cease to the ends of the Earth.

He breaks the bough and cuts the spear in two.

The Bushes and the Obamas, from opposite sides of the American political spectrum, are walking around the ground zero area and greeting people. It's a striking image _ and a glimpse into the role that ex-presidents play as symbols in the United States.

The current and former presidents ran their hands over bronze panels bearing victims' names at the Sept. 11 memorial.

"Ten years later, I'd say America came through this thing in a way that was consistent with our character," President Barack Obama told NBC News. "We've made mistakes. Some things haven't happened as quickly as they needed to. But overall, we took the fight to al-Qaida, we preserved our values, we preserved our character."

"Time to be a big boy. Time to not let things hold you back. Time to just step out into the world and see how things are."

That's what 17-year-old Elijah Portillo said at the site of today's ground zero memorial ceremony in New York, where he arrived early this morning. It's the first time he's attended a memorial here since the attacks killed his father, an architect named Anthony.

He avoided the ceremonies before because he thought he would feel so angry. This year is different.

"I'm not angry," he said. "I wanted to be here."

Two dramatically different perspectives on 9/11 came out of Malaysia today.

Former Malaysian Prime Minister Mahathir Mohamad reiterated an old claim that the U.S. government was behind the attacks, blogging that Arab Muslims are incapable of "planning and strategizing" such attacks, and that the World Trade Center's twin towers "came down nicely upon themselves" and looked more like a "planned demolition of buildings" than a collapse.

Elsewhere in the country, Pathmawathy Navaratnam did something this morning that she's done every day for the past decade: She wished her son, a financial analyst named Vijayashanker Paramsothy who was killed in the attacks on New York, a "good morning."

"He is my sunshine. He has lived life to the fullest, but I can't accept that he is not here anymore," she said. "I am still living, but I am dead inside."

People are waking up to a reminder of the horrors and reverberations of that day: In Afghanistan, two Afghan civilians were killed and 77 American soldiers were injured in a Taliban suicide truck bombing targeting an U.S. base.

Afghanistan's foreign minister said the Sept. 11 attacks bound Afghans and Americans together in a "shared struggle."

But the Taliban emailed a statement to the media: "Each year, 9/11 reminds the Afghans of an event in which they had no role whatsoever. American colonialism has shed the blood of tens of thousands of miserable and innocent Afghans."

It's a little cooler today in New York. But there's a familiar feel in the air.

One of the strongest 9/11 memories for many New Yorkers _ and for people all along the Eastern Seaboard _ was the crisp, sunny weather before the first plane hit the World Trade Center. The day began as a nearly perfect one.

Maybe we shouldn't be surprised about this morning's weather _ this is usually a pleasant time of the year in this part of the world. But there's a familiar feeling in the air.
