Three hundred and thirty-four family members read the names of their loved ones who were killed 10 years ago today. President Barack Obama read from Psalm 46 and former president George W. Bush evoked Abraham Lincoln to commemorate the anniversary of the World Trade Center terrorist attacks at Ground Zero in New York. Six moments of silence are being observed: two to mark the times each plane hit the towers, two when the towers fell, and two when the planes crashed into the Pentagon and a field in Shanksville, Pa. The 10th anniversary also marks the official opening of the National September 11 Memorial—two reflecting pools that sit where the Twin Towers once stood. Watch the ceremony live here.
