WASHINGTON -- Friday, September 11 marks the eighth anniversary of the worst attack ever on American soil.
Now we're seeing new images from that day. Some experts warn that terrorists could be planning to strike again.
The National September 11 Memorial & Museum has launched a Web site with a compilation of amateur video.
A camera in Brooklyn points through a chain-link fence at black smoke pouring from one skyscraper, while a plane pierces another. One videographer asks, what kind of of crazy person would kill themselves like that?
Some of the video is graphic, and a relative of one of the victims says he's glad. He says he doesn't want the day sanitized.
The video will have a warning and will be available online and at the museum that's set to open in three years.
New images have also surfaced of Khalid Sheikh Mohammed, mastermind of the 9/11 attacks.
"When he was captured in March 2003, the capture photos that were released showed him all disheveled, he looked terrible, he was kind of the monster we all had in our minds for who planned 9/11. These photos make him look like he's a peaceful, thoughtful and reflective man, even a pious Muslim," terrorism expert Jarret Brachman said.
The pictures were taken by the Red Cross to send to families of inmates at Guantanamo Bay.
But they hit several jihadist Web sites this week. Terrorism analysts believe they'll be used for a sinister purpose.
"And they're celebrating the release of these photos, they're screaming 'praise be to God' in some cases, in other cases they're saying 'let's go kill Americans', this is a renewed call to them for violence," Brachman said.
And as Americans remember 9/11 and hope another attack never comes, some people are spending time in prayer, seeking a spiritual renewal for the country.
"We have a generation that is hungry, a generation that is inquiring, a generation that needs Jesus and we're sleeping through our moment," said Billy Wilson with the Cry Out America Campaign.
Prayer gatherings are planned from noon to 1:00 p.m. at county courthouses across the nation.
