Boston Marathon Explosion
More from Patricia Zengerle of Reuters on U.S. Secretary of State John Kerry who was asked during testimony before the House Foreign Affairs Committee on Wednesday morning whether he saw any parallels between Boston and other international terrorist incidents.
He said because it hasn’t been determined who was behind Boston it was too early to say.
"Whether it's homegrown, or foreign, we just don't know yet. And so I'm not going to contribute to any speculation on that."
Kerry began his testimony with emotional comments on the attacks in his home city, telling the panel: "It's impossible for me to express my sadness and my anger, frankly, over those terrible events. It's just hard to believe that a Patriot's Day holiday, which is normally such time of festivities, turned into bloody mayhem."
He also appeared to get emotional as he told the story of the granddaughter of a close friend and supporter who is at risk of losing her legs.
