Who carried out the 9/11 attacks? Who were the attackers? How many planes were hijacked?

22 Years ago, 19 terrorists hijacked four passenger planes to use them as weapons of mass destruction committing the deadliest terrorist attack in history.

Who carried out the 9/11 attacks?

2,750 people killed in New York, 184 at the Pentagon, and 40 in Pennsylvania. Fatalities from the heinous crime continue to mount as first responders sickened by the toxic fumes emitted from the rubble of the fallen World Trade Center succumb to the illnesses they’ve developed. 22 years after the 9/11 attacks, the unanswered questions, rage and anger still remain for many Americans.

All 19 suicidal terrorists died in the plane crashes, as well as citizens from 78 different nations, leaving a death toll of over 3,000.

The group which claimed responsibility was al-Qaeda, an international terrorist organisation.

The militants behind the attack

The terrorist hijackers, who were originally from Saudi Arabia and other Arab countries, had been in the US long before the events of September 11 took place. Those who are known to have lived in the states for more than a year took flying lessons at American commercial flight schools, while several others, who managed to get into the country a couple of months before the set date, served as the muscle for the deadly operation.

A total of 19 terrorists managed to hijack four planes without raising suspicions. They carefully chose the flights which were loaded with jet fuel and used the knives and box-cutters, which they easily smuggled on board to take control of the four planes once in the air. Back then, security controls in airports were much more akin to a bus stop than the airports of today, making it easy to smuggle simple weapons onboard.

Osama bin Laden’s role in 9/11

Most-wanted terrorist Osama bin Laden was the leader of the Islamic extremist group al-Qaeda. He claimed responsibility for the attacks, alleging his group was acting in retaliation after the US supported Israel, as well as the global power being an ever-present in the Middle East.

9/11 wasn’t the first of the groups attacks on American targets. Bin Laden took credit for the USS Cole attack in 2000, killing 17, as well as the American embassy bombings in Kenya in 1998. A federal grand jury in the US accused bin Laden on charges related to the East Africa embassy bombings, but as there was no defendant, there could be no trial.

In the meantime, al-Qaeda operatives were busy working on what was about to be the greatest attack of all: the September 11 attacks on the World Trade Center twin towers and the Pentagon, the headquarters of the US Department of Defense and symbol of its military.

The 9/11 Commission, in charge of investigating the events, released a report in 2004 naming Khalid Sheikh Mohammed as the mastermind behind the September 11 tragedy.

Mohammed led propaganda operations for al-Qaeda from 1999-2001. He was captured on March 1, 2003 by the CIA and Pakistan’s Inter-Services Intelligence to be later incarcerated in Guantanamo Bay and charged with 9/11-related war crimes.

In 2011, Osama bin Laden was killed by Navy SEALs during a raid on his compund in Abbottabad, Pakistan, where he had been hiding after fleeing Afghanistan shortly after the US invasion in retailation for the September 11 terrorist attack.
