NEW YORK (AP) -- President Barack Obama is reading from Psalm 46 as part of the ceremony at the World Trade Center site to mark the 10th anniversary of the Sept. 11 attacks.
Each year at the city's Sept. 11 observance, politicians are asked to read passages from selected texts, rather than give speeches, so as not to detract from the centerpiece of the ceremony, the reading of victims' names.
Psalm 46 speaks of God as refuge and strength, dwelling in "his city."
Former President George W. Bush and former New York Mayor Rudy Giuliani were to read as well.
The city is observing the anniversary Sunday at the National September 11 Memorial at the World Trade Center site. The ceremony is also serving as the memorial's official opening.
