(NEW YORK) — Unlike last year, Tuesday’s commemoration of the 9/11 terrorist attacks will be far more subdued.
It was on Sept. 11, 2001 that al Qaeda hijackers flew planes into the World Trade Center towers in lower Manhattan as well as the Pentagon building in Washington, D.C. A fourth plane crashed in a field in Shanksville, Pa., after passengers and crew rushed the cockpit.
Nearly 3,000 people were killed that day, including all 19 hijackers, in the deadliest terrorist strike on U.S. soil that led to two overseas wars while Americans no longer took their national security for granted.
During Tuesday’s ceremonies to commemorate the 11th anniversary of the attacks, no politicians will be allowed to speak at the spot in lower Manhattan that has come to be known as ground zero. As always, the names of the dead will be read by their family members and loved ones.
President Obama and first lady Michelle Obama will observe a moment of silence at the White House while other administration officials plan to visit the Pentagon and the memorial to the victims in Shanksville.
Also, neither Obama nor GOP presidential nominee Mitt Romney plan to run campaign ads Tuesday in deference to the memory of 9/11 victims.
