The events of September 11, 2001 continue to cast their shadow on international policies as the critical turning point that they represented and their repercussions after the attacks claimed the lives of nearly three thousand people, and around 400,000 people were exposed to a toxic dust cloud, most of whom were firefighters and police officers who worked to save as many survivors as possible.

After 22 years, the remains of a man and a woman who died in the collapse of the World Trade Center were identified just before the anniversary of the 2001 disaster, in which two hijacked planes collided with the Twin Towers in New York, in a pivotal event that led many countries to review their security and defense policies.

The authorities also withheld details about the identities of the latest two victims, whose identity was established through DNA analysis, at the request of their families.

The city's mayor and the office of the chief medical examiner clarified that the number of victims whose remains have been identified so far has reached 1,649 out of a total of 2,753 people who died in those events.

On the morning of September 11, 2001, the world awoke to a series of explosions after two planes collided with the World Trade Center, and a third plane struck the Pentagon near Washington, causing significant damage.

A fourth plane also crashed in a field in Shanksville, Pennsylvania, after passengers fought back against the hijackers and took control of it, with the hijackers believed to have intended to use that plane to attack the Capitol building (the seat of the House and Senate) in Washington, D.C.

The total number of victims of the attacks was 2,977 people (not including the nineteen hijackers), most of whom were in New York.

All 246 passengers and crew members aboard the four planes were killed.

In the Twin Towers, 2,606 people were killed either directly or later from their injuries, and 125 people died in the Pentagon building.

The victims hailed from 77 countries, and the city of New York lost 441 members of the rescue, emergency, and firefighting crews who rushed to the attack sites.
