The city marked 25 years since the first terror attack on the World Trade Center with a memorial service Monday in Manhattan.
The service was held at the September 11th Memorial Plaza to remember the victims.
On Feb. 26, 1993, a 1,200-pound truck bomb was detonated in a parking garage beneath the Twin Towers.
The blast killed six people and injured more than a thousand others.
The attack highlighted the growing threat of foreign extremism, and led to safety improvements that helped some people to survive the September 11th attacks eight years later.
Six people were convicted for that bombing and a seventh person was convicted for conspiracy.
