We can't even begin to comprehend what happened earlier today at the Boston Marathon.
There are reports that at least three are dead and scores are injured after two explosions went off near the finish line of the race, just before 3 p.m. this afternoon.
At a press conference, President Obama said, "Michelle and I send our deepest thoughts and prayers to the victims. We don't yet have all the answers...But make no mistake, we will find out who did this...Any responsible groups will find the full weight of justice."
There haven't been many details released about the incident yet. But you can get the latest updates here.
