1993 World Trade Center bombing
The 1993 World Trade Center bombing was an attack on the World Trade Center which killed 6 and injured 1,042.
The WTC became a symbol of American capitalism and economic dominance, and therefore a vulnerable target for Islamic terrorists. In 1993, Islamic terrorists detonated a massive truck bomb in an underground parking lot with the goal of knocking the towers over and killing its capacity of 25,000 workers. This attempt failed, killing only a few, but caused smoke and evacuation of the building.
