September 11 attacks
Four planes were hijacked, three of them were flown into highly symbolic buildings: the Twin Towers of the World Trade Center in Manhattan, New York, and the Pentagon, the headquarters for the department of the Defence of the United States, in Washington. It was a big shock for all Americans as well as the whole world. These attacks were experienced almost in real time byhundreds of millions of viewers worldwide, the images of the plane striking the second tower of the World Trade Center having been broadcast(diifusé) live, as well as the collapse in just few seconds of three towers of the WTC in Manhattan. The psychological(aie) shock was considerable at an international level. These attacks generated powerful and lasting (durable) effects, in particularpolitically and economically(sans a). The national Committee on terrorist attacks against the United States concluded that it was the responsibility of the Al-Qaida network, maintaining that the nineteen hijackers implicated in these attacks were its members and that the leader was Osama Ben Laden.

At the time of the collapse of thetowers only black smoke was visible at the south(saouth) tower escaping from the building.
