United States marks 15th anniversary of 9/11

The United States marked the 15th anniversary of the 9/11 attacks on Sept. 11 with solemn services to commemorate the victims of the deadliest terror strikes on U.S. soil, which changed the world forever.

Nearly 3,000 people were killed on Sept. 11, 2001 when 19 al-Qaeda suicide bombers hijacked four passenger jets, crashing them into the Twin Towers in New York, the Pentagon in Washington and a field in Shanksville, Pennsylvania.

The names of the dead were read out in a remembrance service at Ground Zero in New York on the site of the rebuilt World Trade Center, and President Barack Obama was to address a ceremony at the Pentagon.
"This weekend, we honor their memory once more. We stand with the survivors who still bear the scars of that day," Obama said Sept. 10 in his weekly address.

The 15th anniversary comes with the United States in the midst of a divisive presidential campaign between Hillary Clinton, who was New York senator at the time of the attacks, and Manhattan tycoon Donald Trump.
Both candidates were expected to attend the New York ceremony.

Held at the Sept. 11 memorial, the service paused six times -- to mark the moments when each of the two planes hit, when each tower fell, as well as the attack on the Pentagon and Flight 93 that crashed in Pennsylvania.
