Obama Marks Anniversary of 9/11 at Ground Zero, Pentagon

U.S. President Barack Obama joined former President George W. Bush at the World Trade Center in Manhattan to mark the 10th anniversary of the terrorist attacks that killed almost 3,000 people, reading a passage from the Bible at a ceremony attended by the families of the victims.

Obama was later greeted with cheers and applause when he visited memorials near Shanksville, Pennsylvania, and at the Pentagon, sites where two of the four hijacked airliners crashed. He laid a wreath at each location.
