The deadly bombing at the Boston Marathon Monday has left at least three people dead -- including an 8-year-old boy -- and more than 130 others wounded.
Two explosions rocked the Boston Marathon near the finish line, causing multiple casualties and sending the city into chaos. Another explosion occurred at the JFK Library, but authorities were unsure if the incidents were linked.
The blasts downtown in Copley Square occurred just before 3:00 p.m., according to MyFoxBoston.
