Tuesday marks the 20th anniversary of the 1993 World Trade Center bombing.
A ceremony will be held to honor the six people who died in the 1993 blast in a garage below one of the twin towers. More than 1,000 people were injured.
A moment of silence will be held at 12:18 p.m., the time when a truck bomb was detonated below the north tower.
“It is fitting that, as time goes on, we continue to stop and reflect on this terrible tragedy and the lives that were needlessly lost,” Port Authority Chairman David Samson said in a statement.
Six Islamic extremists were convicted of carrying out the bombing. Four were convicted in March 1994 of carrying out the bombing, and two others, including the mastermind Ramzi Yousef, were convicted in November 1997.
Police Commissioner Ray Kelly said the scale of the attack showed that “terrorism is theater and New York is the biggest stage.”
Jeannine Ali was on the 45th floor when she felt the building shake.
“It was chaotic,” she said in an oral history she recorded for the 9/11 Museum.
After seeing smoke pouring out of the vent, she headed out.
“The stairs were packed. You couldn’t walk down a step until the person in front of you walked down a step. I mean, we were literally back to back to back,” she said, noting that the stairwell had no lights.
She had to count the number of steps out loud.
“There wasn’t the same number of steps on each landing and you couldn’t see,” she said.
Then she stopped at a bar with her co-workers. It wasn’t until hours later when she learned what happened.
“That’s when I found out it was bomb and I collapsed on the floor,” she said.
