This is horrible.
Earlier today, the Boston Marathon was going smoothly, but then three hours after the winners crossed the finish line, TWO explosions near 673 Boylston Street went off and injured spectators.
According to runner Frank Deruyter (who was not injured), "a lot of people [were] down," which included a woman with blood gushing from her leg and other bystanders dripping in blood.
Police are currently investigating the explosions, but no further details have been released.
We hope not too many people were hurt.
