The city began a somber commemoration of the Boston Marathon bombings Tuesday with Mayor Martin Walsh and Roman Catholic Cardinal Sean O'Malley visiting the spots, marked with wreaths, where the twin explosions happened one year ago, killing three people and injuring 264.
Massachusetts Gov. Deval Patrick and the family of the youngest victim, 8-year-old Martin Richard, the mayor and the cardinal stopped twice along Boylston Street near the race's finish line, wherebagpipes played under a drizzly sky.
Vice President Joe Biden is due to speak later today at a memorial near the bombing site.
In a statement, President Barack Obama praised the city's response to the attack.
"Today, we recognize the incredible courage and leadership of so many Bostonians in the wake of unspeakable tragedy. One year later, we also stand in awe of the men and women who continue to inspire us — learning to stand, walk, dance and run again."
After the memorial, which also will feature musical performances, Boston will observe a moment of silence at 2:49 p.m., the time the first bomb went off.
