Twelve years after the Sept. 11 attacks that shook the nation and launched more than a decade of war, Americans are remembering the thousands of lives lost in the terrorist acts.
On Wednesday at 8:46 a.m., the time when terrorists crashed American Airlines Flight 11 into the north tower of the World Trade Center in New York City, hundreds gathered at the site where the towers collapsed. President Barack Obama, joined by Vice President Joe Biden and first lady Michelle Obama, paid tribute on the lawn of the White House and later observed a moment of silence at the Pentagon.
"Our hearts still ache for the futures [that were] snatched away," Obama said at the Pentagon, where another terrorist-piloted plane crashed and killed 184 people. To the survivors of the attacks, he said, “Your lives are the greatest tribute to those that we lost, for their legacy shines on in you.”
Across the country, memorials are being held to commemorate the 12th anniversary of the events that killed a total of 2,983 at the World Trade Center, the Pentagon and a field near Shanksville, Pa.
Below are photos taken from 9/11 observances across the country:
