Maryland ? President Bush on Sunday honored fallen firefighters for their dedication and service to the nation.

From the Sept. 11 attacks to Hurricane Katrina, “there were firefighters from around the country there to help,” Bush said at a ceremony where he and others paid tribute to firefighters killed on the job.

“The bond between firefighters is obviously unique. It is definitely a source of strength and it’s a reminder that the work here is a calling, not a job.”

A plaque with the names of 87 firefighters who died in the line of duty last year was added to the National Fallen Firefighters Memorial on the campus at the National Fire Academy. The names of four others killed in previous years and not honored before also were added.
