Two explosions near the finish line of the 2013 Boston Marathon have the nation on edge Tuesday afternoon (April 15). Country stars like Lady Antebellum, Scotty McCreery, the Band Perry and Lee Brice took to Twitter to send prayers toward those involved. The first blast happened before 3PM ET, with another occurring seconds later.

Police said both explosions were bombs. A third explosion at the JFK library was not thought to be related. Both ABC and CBS news are reporting three people were killed -- including an 8-year-old boy -- and dozens more injured. ABC reports that the first blast came from a running store and knocked the windows out of four nearby buildings. The injured are being treated at tents set up to attend to runners in need, or being taken to nearby hospitals.

Earlier reports that there were additional, undetonated bombs found after the explosions have proven to be untrue, according to Deval Patrick, the governor of Massachusetts  We'll update as more details from the horrific Boston Marathon explosion are confirmed.
