FDNY mourns fallen firefighters on 15th anniversary of 9/11

NEW YORK — The FDNY mourned its fallen brothers Sunday on the 15th anniversary of September 11, 2001.

The department's top brass led a ceremony at the New York City Fire Museum. "This is the sight of the first memorial to our members who were lost," FDNY Commissioner Daniel Nigro said.

The fire department lost 343 men who were unwilling to leave the burning towers. Their pictures fill the 9/11 Memorial Room.

"It's our job to show their legacy. To remind the world, because we can't forget," Chief of the Department James Leonard said.

Katie Thompson, visiting from Oregon, brought her sons to the memorial service. "I hope that it can give them an opportunity to see up close what was given up on 9/11," she said.
