A bell tolled and a moment of silence was held Tuesday to honor six people who died 20 years ago in the first terrorist attack on the World Trade Center.
The ceremony was held at the 9/11 memorial, where the twin towers were destroyed eight years later. About 50 people, including Mayor Bloomberg and former Mayor Dinkins, attended.
The moment of silence was observed at 12:18 p.m., the time when a truck bomb was detonated below the north tower. 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.

Six Islamic extremists were convicted of carrying out the bombing, including mastermind Ramzi Yousef. The 2001 attack brought down the World Trade Center, where more than 2,700 people died.
At first, officials assumed the explosion on a chilly day was an accident. The initial report to police that day called it an apparent transformer explosion at the trade center.
Kelly raced to the scene, where the bomb planted in a parked Ryder van had left a crater half the size of a football field in the trade center garage, causing more than a half-billion dollars in damage.
"I remember seeing this tremendous sea of first-responder vehicles ... and smoke was coming out," said Kelly, who was on his first stint as police commissioner.

The trade center stood in the darkness that night for the first time since it opened in 1973.
It was only the next day, after a utility mishap was ruled out, that authorities "started to come to the conclusion it was bomb," Kelly said.
Investigators then found a vehicle identification number on a piece of the blown-up van that they traced to Mohammed Salameh, who had rented the van.
