The September 11 attacks, often referred to as September 11th or 'nine eleven', were a series of coordinated suicide attacks by al-Qaeda upon the United States on September 11, 2001. On that morning, 19 al-Qaeda terrorists hijacked four commercial passenger jet airliners. The hijackers intentionally crashed two of the airliners into the Twin Towers of the World Trade Centre in New York City, killing everyone on board and many others working in the buildings. Both towers collapsed just in two hours, destroying nearby buildings and damaging others.
