It was a somber day in Boston Tuesday as those who lost their lives and were injured were honored with a flag-raising ceremony and a moment of silence at the finish line of the Boston Marathon. This week marks the one-year anniversary of the explosions that killed three and wounded more than 200 people. 

Tuesday was a day of tributes, also honoring the first responders, medical personnel who helped the victims and the MIT police officer killed when one of the alleged bombers tried to steal his gun three days after the bombing attack.  

Do most residents of Boston feel the city has recovered one year after the Boston Marathon bombings?

"No, not entirely. There's still a lot of scars," one woman said. 

Despite increased security for this year's marathon, some residents say they will avoid the event because of what happened a year ago. But this man says he'll be there.

"It won't prevent me from going to the Marathon at all. And I just find it great that Boston comes together after a tragedy like that and that we come out even stronger," he said. 

On the afternoon of April 15, 2013, two homemade pressure cooker bombs went off just 12 seconds apart on Boylston Street near the marathon finish line.  

Spectators, volunteers, police and first responders raced to the scene to help the wounded. In all, the Boston Marathon bombings killed three people and injured more than 150.

President Obama issued a statement today, marking the anniversary of the horrific event.
