11th September 2001

One of the most spectacular attacks in history is the terrorist attack in the United States, which killed about 2976 victims and 19 terrorists.
The attacks, which took place on September 11, 2001, in which 19 Al-Qaeda (Wahhabi militant networks) hijacked four US aircraft, were coordinated terrorist attacks against the United States and are the most popular attacks ever committed against the United States. Specifically, 27 Al Qaeda members first tried to join the US and join the attacks, but only 19 of them participated, because some of the members were denied a visa to enter the United States - Remzia Binalshib, then Muhammad Kahtani was barred by US immigration authorities at the Orlando International Airport and other members failed to join the attacks. While one of the members of Zakarias Musavi, who was not involved in the attacks because the al-Qaeda hierarchy had doubts about its reliability, pleaded guilty in 2005 and was sentenced to life in prison.
Osama bin Laden (who was a multimillionaire and al Qaeda leader), Ajman al-Zawahri (current al Qaeda leader or former member and senior official of Islamist organizations) and several others issued a fatwa (order) that cited several motives for fighting the US and that order accused the US of:

- exploit and deplete the resources of the Arabian Peninsula;
- pursue a policy of leaders in these countries;
- support dictatorial regimes and monarchies in the Middle East, thereby oppressing its population;
- maintain military bases and installations in the Arabian Peninsula in order to threaten nearby Muslim countries;
- intend to make their presence divisive among the Muslim states by weakening them politically.
While the Gulf war and the US sanctions and bombing of Iraq have been presented as evidence of all these allegations and a sufficiently justifiable motive to carry out an attack that will hit the US economically, socially, culturally and militarily, it has also left consequences in many to other parts of the world.
The attackers turned the hijacked planes into the largest suicide bombs in history.
Two planes hit the World Trade Center (STC) in Manhattan, New York, one each in a soliton in 17 min difference, after which both solitons crashed. A third plane crashed into the Pentagon, the headquarters of the US Department of Defense in Washington, and a fourth crashed in rural Pennsylvania because of resistance from hijackers. However, at first glance, when the first Boing 767 plane crashed into the north tower of the STC between the 94th and 98th floors, the event was considered a tragic accident, but when after about 25 minutes another Boing 767 plane crashed into the south tower of the STC - and between the 78th and 84th floors it was clear that it was a terrorist attack, with US President George W. Bush calling the events a "national tragedy". After the third Boeing 757 aircraft crashed into the Pentagon, US airspace was cleared and all flights diverted to Canada. The White House, the State Department and the US Congress were evacuated. And, as far as the fourth plane is concerned, it is assumed that the passengers heard about the attacks on the STC and the Pentagon and therefore disabled the terrorists, which caused the plane to crash. When the south tower of the STC collapsed, more than 350 firefighters and 60 police officers were rescued to rescue the people inside it. Soliter collapsed because a plane fuel fire melted a load-bearing steel structure. The UN building and the New York Stock Exchange were then evacuated. All of southern Manhattan was shrouded in thick smoke after the STC's north tower collapsed completely. The casualties are in the thousands, 265 in four aircraft, 2,595 including 343 firefighters, 23 New York police and 37 port police officers in the STC and 125 civilians and military personnel at the Pentagon. In addition to the STC tapeworm, five other buildings and four subway stations were also destroyed or badly damaged. And communication equipment such as radio, tv and mobile transmitters were unusable. From the STC, about 200 people jumped to their deaths due to the desperate situation of smoke and fires from aircraft fuel. Some of them climbed upstairs after the plane crash, hoping to be rescued by helicopters on the roof, but there was no plan for such a rescue opportunity. About 1,366 people were trapped on the floors above and none survived in the north solitaire, and in the south there were about 600 captured, with 18 escaping in time before the solitaire collapsed. The victims included two people from Serbia, Vladimir Tomasevic and Bojan Kostic.
As for the fourth plane, it is alleged that the hijackers intended to hit the Capitol, the US Congressional building, the White House or Camp David, where President George W. Bush went for safety. Whereas, a black box shot reportedly revealed that two passengers had tried to retrieve the plane from the hijackers, where the hijackers knocked the plane over an unsuccessful attempt to defeat them. And, so the plane crashed in a field near Shanksville, Pennsylvania. While the organizer is AAnd Qaeda, Sheikh Muhammad reportedly said that this flight was supposed to hit the US Assembly building.
Many states have introduced strict anti-terrorism laws and taken steps to cut off terrorist financing, including freezing bank accounts that were suspected of being used in terrorist financing.
More recently, the incidence and intensity of terrorism and violence has been a major security risk and a challenge for the security structures of all countries. At the same time, modern terrorism brings us a new form of endangering human lives, as well as difficulties in predicting how these attacks will be carried out.
