NEW YORK - The 12th anniversary of the Sept. 11 attacks began with solemn bell tolls and a moment of silence at the World Trade Center site.
The moment of silence at 8:46 a.m. Wednesday marked when the first plane hit the twin towers in 2001. Families of the victims started reading aloud the names of those who died.
A second bell tolled at 9:03 a.m. to mark when the second plane hit the twin towers. Then the reading of the names resumed.
During a ceremony at the Pentagon, President Barack Obama vowed to "defend our nation" against the threats that endure, even though they may be different than the ones that faced the country 12 years ago today.
Among those gathered were family members of those killed 12 years ago today.
A memorial ceremony was also held in the Shanksville, Penn. field where United Flight 93 went down. 33 passengers and seven crewmembers died in the crash.
Flight 93 was traveling from Newark, N.J., to San Francisco, when it was hijacked with the likely goal of crashing it into the White House or Capitol.
