Urban terrorism

A variety of methods for committing urban terrorism have been employed in recent history including car bombs, explosive vests, and in the case of the September 11 attacks, hijacked airplanes.

On February 26, 1993, at 12:17 p.m., a Ryder truck filled with 1,500 pounds (680 kg) of explosives, planted by Ramzi Yousef, detonated in the underground garage of the North Tower in Lower Manhattan, New York City, United States.

Many people inside the North Tower were forced to walk down darkened stairwells that contained no emergency lighting, some taking two hours or more to reach safety.

[10][11] The hijackers intentionally crashed two of the airliners into the Twin Towers of the World Trade Center in New York City, killing everyone on board and many others working in the buildings.

[13] In addition, there is at least one secondary death – one person was ruled by a medical examiner to have died from lung disease due to exposure to dust from the World Trade Center's collapse.
