Seventeen years after 9/11, a former cameraman from the American news channel CBS News shared new images of the attacks on YouTube.
He shows the rough images, which show how people run away from the site and are completely dusted.
On the images you also see how emergency services try to save the many victims and do their utmost to save as many people as possible. The cameraman was also able to film the collapse of the second WTC tower. A huge cloud of dust came upon him and you see people running for their lives.
Almost 3,000 people died in the attacks on 11 September 2001.
