As the nation and the world mark the 10th anniversary of the Sept. 11 terrorist attacks, Associated Press journalists are tracking down the most salient details of the day, and capturing the mood, from ground zero to Afghanistan and everywhere in between.

Here, in real time, are the latest updates on how the day is unfolding, together with occasional flashbacks to AP reports distributed on Sept. 11, 2001. The archival material has been left as it was transmitted 10 years ago, including the original typos, as well as information from AP sources that later turned out to be incorrect.

Many are in tears. Others simply look somber. Still others show little emotion at all _ they almost look like tourists.

Most have two things in common, besides the awful fate that brought them together here: They all seem to want to take pictures of loved ones' names, and they're touching the words in the stone, pressing their palms to them or running their fingers gently along the letters.

Others are using pencils and paper to make etchings of the names, so they can bring a piece of this memorial home with them.

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."

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.
