President Obama on Thursday eulogized the three young victims of Monday’stwin bombings at the Boston Marathon and offered encouragement to the scores of people injured in the attacks, telling a packed cathedral in the city’s South End that “Boston’s your home town, but we claim it a little bit, too.”

“Every third Monday in April, you welcome people from all around the world to the Hub — for friendship and fellowship and healthy competition,” Obama said during an interfaith service of healing held at the soaring Cathedral of the Holy Cross. “A gathering of men and women of every race and every religion, every shape and every size, a multitude represented by all those flags that flew over the finish line.”
