THE horrific events of 9/11 continue to shape the world we live in, 18 years after they took place.
Thousands were killed during the terrorist attacks on New York, Washington and Pennsylvania.
When was 9/11?
On September 11, 2001, a group of al-Qaeda terrorists hijacked four airliners.
Two planes – American Airlines Flight 11 and United Airlines Flight 75 – crashed into the North and South towers of the World Trade Center complex in New York City.
Another was flown into the Pentagon in Washington DC and the fourth crashed into a field in Pittsburgh, Pennsylvania after a struggle between the hijackers and passengers.
How many people died in the terror attack on the World Trade Center?
Of the 2,996 who died on 9/11, including the 19 hijackers, 2,606 were killed at the World Trade Center and the surrounding area.
Both towers collapsed following the impact, with debris causing more deaths and injury on the streets below.
Many people including the emergency response teams lost their lives trying to save others.
It was the worst loss of life due to a terrorist incident on US soil.
In 2017, another victim of the attack on the World Trade Center in New York City was identified.
The male victim is the 1,641st person to be identified out of those who died in the Twin Towers’ attack.
In July 2019, the 1,644th victim of 9/11 was identified as a woman – her identity was withheld at her family’s request.
Those killed included 67 British people and around 300 New York firefighters.
Among those who died was “The Falling Man”, a figure photographed falling from the North Tower of the World Trade Center at 9.41am.
Many of those trapped in the towers threw themselves out of windows as they realised they wouldn’t be able to make it out in time.
The person in the photograph has never been identified, but it’s thought he worked at the Windows of the World restaurant in the North Tower.
About 40 per cent – or 1,109 victims – of the reported 2,753 missing from the Twin Towers remain unidentified.
In 2011, 10 years after the attacks, American officials said more than 18,000 people were still suffering from illnesses linked to the dust.

Where is the memorial?
The National September 11 Memorial & Museum is at the original World Trade Center site.
The memorial features two huge, deep pools at the base of the old World Trade Center towers.
Around the edges of the pools, each almost an acre in size, the names of those who were killed in the attacks are embossed in bronze panels.
It includes the names of 2,996 people killed by al-Qaeda in New York, the Pentagon and in Pennsylvania.
