U.S. remembers infamous day
Other ceremonies are being held throughout the day around the country, including in Washington and in Pennsylvania. Barack Obama and John McCain are due at ground zero to pay silent respects.
Maureen Hunt, wearing a T-shirt with a picture of her sister, Kathleen, a 9/11 victim, said that it was comforting to be at the ceremony with so many who have lost loved ones.
“This is a place for us to meet,” said Hunt, who has come each year to pay her respects. “It is not getting easier to attend these ceremonies.”
