BOSTON (CBS/AP) — Mayor Martin Walsh and the city of Boston paid tribute to the two fallen firefighters by raising the Boston Fire Department flag at City Hall Plaza on Friday.

A moment of silence was also held for Lt. Edward Walsh and Firefighter Michael Kennedy, who perished while fighting the brownstone blaze in the Back Bay. Walsh was married with three children under age 10. Kennedy, a former Marine, was single.

Mayor Martin Walsh said Friday the courage of Walsh and Kennedy will never be forgotten, and “words cannot repay the debt of gratitude” the city owes them and their families.

“They put themselves in harm’s way so that others might be safe,” Mayor Walsh said. “As we reflect on their extraordinary actions, we must not forget that this is what they do every day of their working lives.”
