A moment of silence as fire fighters remember those who died in the 9/11 attacks.

London Remembers 9/11

A solemn day at the Fire Department’s Memorial Headquarters as Londoners¬†gathered to commemorate the 13th anniversary of the 9/11 attacks in New York City.

Nearly 3,000 people died when highjackers flew two planes into the World Trade Centre, causing the Twin Towers to collapse. Among the dead were over 400 first responders.

Planes also crashed into the Pentagon in Washington and in a field in Pennsylvania.

“It was surreal, we were shocked. It was the single largest loss of life in the first responder community. I think if we let our past slip away then we’ll forget the lessons that we learn from our past,” says John Hassan, president of the London Professional Fire Fighters Association. “We have to acknowledge what people gave up and the ongoing sacrifices in other countries, other cities and here. It’s just as relevant today as it was then. We never know when something catastrophic will happen.”

Memorial services are also being held in New York, Washington and Pennsylvania.

A total of 24 Canadians died in the attacks.
