Hundreds of firefighters from across America crowded into New York’s St Patrick’s Cathedral on Saturday to pay their respects to colleagues who were killed in the September 11 attacks.
The memorial service was held just minutes from ground zero, where the twin towers of the World Trade Centre once stood.
The names of all 343 New York firefighters who died during the tragedy 10 years ago on Sunday were read out during the ceremony.
Exposure to the toxins from the collapsed skyscapers killed 55 others. Many more are suffering long-term illnesses.
“Our city was lucky to have a group of men and women who can overcome the natural instincts of fear to serve others. We saw that in such tragic clarity on the morning on 9/11,” said New York Mayor Michael Bloomberg, in a speech to the victims’ relatives.
