The world was frozen for a moment when everyone saw the terrorist attack on America on September 11, 2005. The whole world got stunned because of the rise of terrorist groups around the world. They pose a big threat to the developed nations. Flights were hijacked and made to strike on buildings like twin towers and pentagon. These buildings were targeted because twin towers were one of the tallest buildings in United States of America and pentagon is the place where whole business transaction of America took place.

In a few minutes the whole twin towers got collapsed leaving only ashes behind. Many people lost their lives and it was considered a big trounce for United Nations since no one could find out that a major disaster is going to happen. Even the developed United States of America was very much lacking in the security point of view as more than six terrorists entered into the flight and hijacked. In America the security conditions was worse at that time which led to this terrorist attack.

United Nations found out that Osama bin laden, the boss of al-Qaida was the terrorist master mind behind September 11 attack. The U.S.A army searched for him but it could not succeed. Some say that he is dead but some say he is alive. No matter whether U.S army have destroyed the terrorist group or not still September 11 attack is lingering in everyone’s mind even though the days pass on.
