Two explosions near the finish line of the Boston Marathon this afternoon killed at least two people and injured at least 90 more. The cause of the explosions is not yet clear. CNN is calling it a “terrorist attack.” President Barack Obama will deliver televised remarks shortly. I will update later with more news, but I wanted to put up a post for anyone in the Bleeding Heartland community who wants to discuss the tragedy. Statements released by Representatives Bruce Braley and Dave Loebsack are after the jump.

UPDATE: At least three are confirmed dead, more than 100 injured. No individual or group has claimed responsibility for the bombs. Two unexploded devices were found elsewhere in Boston.

Organizers of a half-marathon and 5K race in Council Bluffs say the events will take place as scheduled this Sunday, with a “security presence.” UPDATE: There will be extra security at a Linn County race this weekend as well.

Contrary to some speculation on twitter, today is not the anniversary of the Oklahoma City bombing. That happened on April 19, 1995.

Statement from Representative Bruce Braley (IA-01):

“I’m shocked and appalled at what transpired today at the Boston Marathon. My thoughts and prayers go out to the runners, volunteers, and spectators involved in this tragic event.”

Statement from Representative Dave Loebsack (IA-02):

“The events that happened today in Boston are appalling. My thoughts and prayers are with all those injured and the families and loved ones of those who were lost.  I would like to thank the first responders, members of the National Guard, and all those who responded and provided assistance to those who needed it.  As a nation, we stand with the people of Boston.”
