Tragedy struck Massachusetts today, as dual explosions disrupted the 177th running of the Boston Marathon. Of the 27,000 athletes participating in this year's contest, at least two were reported dead and 73 more injured as of 7:00 PM on Monday, April 15.

President Obama addressed the nation shortly after 6:30 PM, asking his fellow countrymen to "say a prayer for Boston" and adding "Michelle and I send our deepest thoughts and prayers to the families of the victims in the wake of this senseless loss."

Musicians around the globe, many of whom call Boston home, took to Twitter to express their condolences to a city and country in mourning.
