THESE ARE the harrowing pictures of 9/11 23 years ago caught on camera by a photographer originally from north Wales.

Today (September 11), marks 23 years since al-Qaeda terrorists hijacked four passenger planes and flew them into the Twin Towers and the Pentagon.

Just under 3,000 people lost their lives during the incident now known worldwide as '9/11'.

There were no survivors from any of the flights; 2,753 victims died when the World Trade Centre was hit, and 184 people were killed in the attack on the Pentagon.

A total of 343 firefighters, 60 police officers and eight private emergency medical technicians and paramedics were also killed.

Back in 2021, on the 20th anniversary of the tragedy, reporter Arron Evans caught up with photographer Dan Callister who shared his pictures from the scene.

Dan, originally from Ruthin, was 26 years old at the time of the attacks and was working as a photographer for a New York company.

On the morning of September 11 2001, he received a call from a reporter saying a small plane had hit the World Trade Centre.

Grabbing his camera and lenses, Dan jumped into a cab and headed towards the towers.

The former Ysgol Brynhyfryd student was just 200 yards from the World Trade Centre, when he started taking pictures of the second tower which was still standing.

Dan (below) captured hundreds of images that day, which were screened across the globe.

His image of fire lieutenant Reilly was used by the former US President George Bush during one of his many speeches after the attacks.

He still lives in New York to this day, working as a freelance editorial, commercial and wildlife photographer.

Dan has once again given us permission to use his pictures from that fateful day 23 years ago, which you can view in the gallery above.

He says the date 'always holds significance' to him and that he 'always shares a thought for those who never came home'.
