Twin Towers, the
two very tall skyscrapers that were part of the World Trade Center, a group of buildings in Manhattan, New York City. When they were built in the 1970s, the towers were the tallest in the world. In 1993 terrorists killed six people with a bomb they had left there. On 11 September 2001, terrorists flew two planes filled with passengers into the Twin Towers which caused them to fall down. Almost 3000 people were killed, including everyone on the planes and many firefighters and police officers who were trying to save people in the buildings. It is believed that the terrorist organization al-Qaeda was responsible for the attack.
