Boston (CNN) – President Barack Obama said whoever is behind the Boston Marathon bombings will be caught.
"Yes, we will find you. And yes, you will face justice," Obama said at an interfaith service commemorating the victims. "We will find you. We will hold you accountable. But more than that, our fidelity to our way of life ... will only grow stronger, for God has not given us a spirit of fear and timidity, but one of power and love and self-discipline."
Boston's resolve is the greatest rebuke to whoever committed Monday's Boston Marathon bombings, Obama said.
"If they sought to intimidate us, to terrorize us, to shake us from those values ... who make us who we are as Americans, it should be clear by now that they picked the wrong city to do it (in). Not here in Boston."
The president said he came with a message on behalf of all Americans: "Every one of us has been touched by this attack on your beloved city. Every one of us stands with you, because after all, it's our beloved city, too. Boston may be your hometown, but we claim it, too."
