Today marks the 21st anniversary of the suicide bombing of the Twin Towers of the World Trade Center by al-Qaeda.

On the morning of Tuesday, September 11, 2001, 19 members of the Al-Qaeda terrorist group hijacked four commercial airliners. They were planning to travel from the Northeast to California.

The terrorists first hit the twin towers of the Walled Trade Center in New York City with two planes. A third plane hit the Pentagon in Virginia. And the fourth plane was planned to hit a federal government building in Washington DC. But the plane exploded in a field due to protest by one of the passengers.

About 3,000 people lost their lives in the Al-Qaeda terrorist attack. Besides, more than 25 thousand people were injured. Many of them suffer from long-term physical complications for the rest of their lives.

In addition to civilians, 340 US firefighters and 72 law enforcement officers lost their lives.

And due to the destruction of various structures, there is a financial loss of at least 10 billion US dollars. It took eight months to remove the rubble of the Twin Towers. And within a year, the military headquarters, the Pentagon, was rebuilt.

It was after that attack by al-Qaeda that the United States officially launched a declaration against terrorism and launched an attack against the Taliban in Afghanistan.

And according to Article 5 of the NATO military alliance, the member countries also started attacking Afghanistan under the leadership of the United States. Osama Bin Laden, the head of al-Qaeda at the time, hid in the White Mountains to avoid arrest. He initially denied involvement in the attack on the Twin Towers, but in 2004 bin Laden formally claimed responsibility for the attack.

At that time, al-Qaeda said that the US support for Israel, the sanctions on Iraq, the presence of US troops in Saudi Arabia motivated them to attack the United States.

After more than a decade on the run, the United States military killed bin Laden, who was hiding in Pakistan, on May 2, 2011 under the administration of President Barack Obama.

After the attack on the Twin Towers, all the countries of the world started taking strict measures against terrorism. Almost every country has passed laws including formation of special forces to combat militancy.
