Five videos were found in bin Laden's compound in Abbottabad, Pakistan, after U.S. Navy Seals stormed the compound and killed bin Laden. At left, Khalid Shaikh Mohammed, during his arrest in Rawalpindi, Pakistan, on March 1, 2003. Mohammed has been in U.S. custody since 2003, and will face a military trial at the Guantanamo Bay detention facility, charged with 2,973 individual counts of murder among other crimes. Right, al-Qaida's former second-in-command (now top commander) Ayman al-Zawahiri speaks from an unknown location in this still image taken from video uploaded on a social-media website on June 8, 2011. Osama bin Laden's longtime lieutenant said the United States faces rebellion throughout the Muslim world after killing the Qaida leader, according to a 28-minute YouTube recording. In what appeared to be his first public response to bin Laden's death in a U.S. commando raid in Pakistan, the Egyptian-born Zawahiri warned Americans not to gloat and vowed to press ahead with al-Qaida's campaign against the United States and its allies.

Gavriushin has buried rocks from Ground Zero under these tombstone towers, far from the place Yelena died—a place he can no longer afford to visit. And so, as the 10-year anniversary of the terrorist attacks approaches, he mourns for her here, at his own Ground Zero. He remembers frantically calling his daughter that day amid the terrified crowds in Brooklyn, where he was at the time: "She never answered." (Mindaugas Kulbis/AP) View original.

34 Blood-stained shoes worn by Linda Lopez as she evacuated from the 97th Floor of Tower 2 on Sept. 11, 2001, are seen in this Aug. 22, 2011, photograph before becoming a part of the National September 11 Memorial & Museum in New York. Lopez was at work at the Fiduciary Trust Company on the South Tower's 97th floor when the first plane crashed into North Tower, sending a fireball past their window and radiating a heat that she said felt like being sunburned. There was quickly a sense of confusion: Was it a bomb? Were the rumors that it was a plane crash true? Should people in the South Tower ignore the advice coming over the public address system to stay put and evacuate instead? Lopez felt she had to get out. She had reached only as far as the 61st when she was thrown against a wall as the second plane crashed into the floors above her. Taking off her shoes, she continued to head down the stairs, passing firefighters heading in the opposite direction. She ran barefoot out of the building, across broken glass and other debris. "Lady, your feet are bleeding," someone said to her as she paused a few blocks away in relative safety. She put her shoes back on, and began learning the details of what it was she had just escaped from. The museum, which occupies seven stories below the ground of the World Trade Center site, is still being built at the site of the fallen towers. It is due only to open in 2012, on the 11th anniversary of the attacks. (Lucas Jackson/Reuters) View original.
35 A recovered New York City Fire Department Squad 252 helmet belonging to deceased FDNY member Kevin M. Prior is seen in this Aug. 22 photograph before becoming a part of the National September 11 Memorial & Museum in New York. Prior, a firefighter with Brooklyn's Squad 252, can be seen in video footage of the North Tower lobby recorded after the first plane hit getting ready to go upstairs. Responding to a mayday call sent out by fellow firefighters encountering breathing problems, he and five other members of the squad are thought to have been on a floor in the 20s when the tower collapsed. Prior's body was found three weeks after the attacks and was buried on Long Island, but his mother was troubled that his helmet had not been returned to the family, and said as much in a television interview. An employee at the city's Office of the Chief Medical Examiner happened to catch the broadcast, recognized Prior's squad and badge numbers, and hand-delivered the badly damaged helmet to his grateful family.
