VIDEOS/PHOTOS: Today marks a grim anniversary in New York City history - on Feb. 26, 1993, shortly after noon, terrorists set off a homemade bomb in the parking garage beneath the World Trade Center's Twin Towers.
Six people were killed, including a pregnant woman, and more than 1,000 were injured in the massive explosion and smoky aftermath. The towers were shuttered for weeks, and in 1995, a memorial was dedicated to the victims in Austin Tobin Plaza at the World Trade Center.
Almost nine years later, the Twin Towers were destroyed on 9/11, claiming almost 3,000 lives that day, a toll that continues to mount from diseases related to the attack. A small part of the memorial for the victims of the 1993 bombing was discovered in the ruins of the complex.
