The celebrating Palestinians on 9-11 was A HOAX

Via Das Erste (Google Translate):

If you look closely at the full, unbroadcast footage, you'll notice that the street around it is quiet. Just a group of excited children in front of the camera. The woman, who will be remembered for her exuberance of joy, shortly afterwards moves on, unmoved. Noticeably a man in a white T-shirt. He encourages the children and he always gets new people involved.

The woman who just left says today that she was promised cake if she was happy in front of the camera. She was horrified when she saw the images on television. She was never happy about the attack on the USA. Truth? Staging?
