Three people are reported dead and at least 133 injured at The Boston Marathon, which has now been shut down after two bomb explosions near the finish line, on this Patriot's Day.
Witnesses reportedly heard two loud explosions near the finish line inside the Fairmount Copley Plaza Hotel that sounded like two claps of thunder at storefront windows nearby were blown out.
Hundreds of people have now been evacuated as a result of the two severe explosions. The marathon has now been suspended.
The Boston police bomb squad confirms there was an incident but did not immediately give details. Police, fire and medical technicians were responding. According to news reports, the emergency response came within seconds of the two explosions.
There were approximately 26,900 runners participating in the Boston Marathon this year, representing nearly one hundred countries.
