A moment of silence was observed at 12:18 p.m., the time when a truck bomb was detonated below the north tower on Feb. 26, 1993. The victims' names were read by family members before bagpipers played "Amazing Grace."

More than 1,000 people were injured in the 1993 blast in an underground garage below one of the towers. It was the first dramatic demonstration that "terrorism is theater and New York is the biggest stage," Police Commissioner Raymond Kelly said last week.
