The 9/11 terror attack in which nearly 3,000 people were killed when hijackers flew commercial airplanes into New York’s World Trade Centre, the Pentagon, and a field near Shanksville, Pennsylvania.
The September 11 attacks had shaken the United States and had a huge impact globally as it was one of the most dreadful attacks ever made by the terrorist group al-Qaeda.
Nineteen al-Qaeda terrorists hijacked four US passenger planes between 8 and 9 am. Two of the planes crashed into the Twin Towers of the World Trade Center complex in Manhattan.
The third plane crashed into the Pentagon, the building that houses the headquarters of the US Department of Defense, in Virginia. The fourth plane crashed into a field in Pennsylvania after passengers tried to fight back.
Within two hours, the two 110-storey towers at the World Trade Centre collapsed. The debris of the Twin Towers led to the collapse of other buildings in the complex
The clean-up of the World Trade Center site was completed in May 2002 and the Pentagon building was repaired within a year. The investigation into of 9/11 attactks – code-named “PENTTBOM” – was the FBI’s largest investigation ever.
More than half of the agents in FBI worked to identify the attackers and their supporters. It included over half-a-million investigative leads, including several hundred thousand tips from the public. The crash sites were also the largest crime scenes in FBI history
These include the National September 11 Memorial and Museum in New York City, the Flight 93 National Memorial in a field in Stonycreek Township in Pennsylvania, and the Pentagon Memorial in Arlington County in Virginia.
Meanwhile, New York city will hold its annual ceremony remembering the people who lost their life in the 9/11 attack today amid the COVID-19 pandemic.
