In a ceremony in Kabul, United States-led NATO forces closed its combat command in Afghanistan. The NATO flag was lowered and put away, marking the withdrawal of most foreign troop in Afghanistan more than 13 years after the country was invaded in the wake of the Sept. 11, 2001, terrorist attacks. The intention behind the invasion was to crush the terrorist organization behind the attacks–al-Qa’ida–and to capture its leader–Osama bin Laden.

NATO forces quickly brought down Afghanistan’s Taliban-controlled government, which had sheltered al-Qa’ida. However, much of the al-Qa’ida organization escaped into other countries, particularly across the border into Pakistan. (American military forces finally tracked down and killed bin Laden in Pakistan in 2011.)

After 13 years of intermittent combat, the Taliban remains an active force in Afghanistan, regularly launching offensives and carrying out terrorist attacks. The United States currently plans to maintain 13,000 troops there. The remaining U.S. forces are to continue the training of the Afghan army.

Today, 13 years after a terrorist attack destroyed the World Trade Center in New York City, the first tenants begin moving into One World Trade Center, one of several new buildings constructed at the site. The skyscraper, the tallest building in the United States, overlooks the National September 11 Memorial Museum, a memorial to the nearly 3,000 people killed on that date in 2001 in multiple attacks by al-Qa’ida militants. The original Trade Center’s twin towers collapsed after hijacked passenger jets were crashed into them.

The building’s first tenant is Condé Nast, which publishes 18 magazines, including The New Yorker, Vogue, Vanity Fair, Glamour, Bon Appétit, and Brides. The company will occupy floors 20 through 44. The move into One World Trade Center is expected to accelerate the growth of commercial and residential developments in Lower Manhattan, which has been dominated by financial institutions.

The 104-story One World Trade Center is 1,776 feet (541 meters) tall, a reference to the year 1776, when the United States declared its independence from Great Britain. The skyscraper has 3 million square feet (278,700 square meters) of space, including commercial offices, observation decks, parking, and restaurants. An observatory is expected to open in spring 2015. The building’s 408-foot- (124-meter-) high spire will function as a broadcast antenna for the region’s media outlets.

Standing before one of the foundational walls of the destroyed World Trade Center, President Barack Obama and other speakers today helped to officially dedicate the National September 11 Memorial Museum. The museum was built to honor the memory of those killed in the terrorist attacks of September 11, 2001, and the February 26, 1993, World Trade Center bombing. In his remarks, President Obama described the museum as a “sacred place of healing and hope” and insisted that “no act of terror can match the strength and character of our country.”

The September 11 terrorist attacks, also called 9/11, were the worst acts of terrorism ever carried out against the United States. The terrorists hijacked four commercial jetliners and crashed two of them into the twin towers of the World Trade Center in New York City and one into the Pentagon Building near Washington, D.C. Hijackers crashed the fourth jet in a Pennsylvania field to prevent it from being reclaimed by passengers. The attacks killed about 3,000 people, including the 19 hijackers.

The museum lies seven stories below the ground-level National September 11 Memorial, which includes twin reflecting pools that lie in the footprints of the North and South towers. The walls of the new museum are lined with some 23,000 photos and images connected to the attacks. On display are 12,500 objects associated with the tragedy, including 2,380 objects donated by survivors, families of the dead, first responders, and others involved in the rescue efforts and the investigation and cleanup. Visitors can also listen to 1,995 oral histories and watch 580 hours of film and video. In addition, the museum incorporates remnants of structural columns that now mark the footprints of the original Twin Towers and sections of the retaining wall, known as the slurry wall, originally built to keep the Hudson River from flooding the World Trade Center site when it was first excavated. Earlier this week, about 14,000 unidentified or unclaimed remains from people killed on September 11 were moved to a repository adjacent to the museum.  The museum is “a collective story about how people can be good to one another in times of crisis,” curator Jan Ramirez told CNN. “We’ve put out our first draft of history.”

The installation of the silver spire topping One World Trade Center was completed today, bringing the structure to the height of 1,776 feet, a reference to the year of America’s declaration of independence from Great Britain, 1776. The skyscraper stands at the site of the September 11, 2001, terrorist attacks. Below the new tower is a memorial to the nearly 3,000 people killed in multiple attacks by al-Qa’ida militants. The original Trade Center’s twin towers collapsed after hijacked passenger jets were crashed into them.

When the interior of new Trade Center is finished, the skyscraper will house 2.6 million square feet (242,000 square meters) of commercial office space, plus observation decks, restaurants and other public facilities. The 408-foot- (1,241-meter-) high spire will function as a broadcast antenna for the region’s media outlets.

The 11th anniversary of the September 11, 2001, terrorist attacks was observed today in New York City; Arlington, Virginia; and Shanksville, Pennsylvania. In New York, relatives of the victims of the World Trade Center attacks read out the names of the dead. Governor Andrew M. Cuomo of New York, Governor Chris Christie of New Jersey, New York City Mayor Michael R. Bloomberg, and former Mayor Rudolph W. Giuliani attended the observance but did not speak.

In Arlington, President Barack Obama addressed survivors and relatives of the 184 people killed at the Pentagon, the U.S. Department of Defense headquarters. He declared that their loved ones would never be forgotten and that the dead had “helped us make the America we are today.”

Vice-President Joe Biden was the principal speaker at the Flight 93 National Memorial in Shanksville. In remembrance of the dead, President Obama and Vice-President Biden and their Republican challengers, Mitt Romney and Paul Ryan, set aside campaigning for the day.

Nearly 3,000 people were killed on Sept. 11, 2001, in attacks by members of al-Qa`ida, the Afghanistan-based terrorist organization headed by Osama bin Laden. After hijacking four commercial airliners, the terrorists flew two jets into the Trade Center twin towers, which subsequently collapsed. Terrorists crashed a third airliner into the Pentagon. The attackers in the fourth airliner were overtaken by passengers, preventing them from crashing the plane into another Washington, D.C., landmark, possibly the White House or Capitol. The jet went down in an open field near Shanksville, killing all aboard. The September 11 terrorist attacks prompted the administration of President George W. Bush to send forces into Afghanistan in October 2001 to clean out terrorist camps. That war continues in 2012.

Although not yet topped out, the new One World Trade Center yesterday surpassed the height of the Empire State Building as New York City’s tallest building. One World Trade Center is currently under construction on the site of the original World Trade Center, the twin towers destroyed in the terrorist attacks on Sept. 11, 2001. Yesterday’s work on the structure brought the unfinished frame of the building to a little more than 1,250 feet high (381 meters), the level of the Empire State Building’s highest observation deck.

When complete, One World Trade Center will be topped by a 408-foot (124-meter), cable-stayed spire, making it 1,776 feet (541 meters) tall, the tallest building in the United States. The current highest building in United States is the Willis Tower in Chicago. Formerly named the Sears Tower, the building is 110 stories, reaching 1,450 feet (442 meters) high. The north tower of the original World Trade Center was 1,368 feet (417 meters) in height.
