President Barack Obama is reported to have reached out to the Mayor of Boston to offer assistance.
Sports producer Steve Silva told Boston.com "I saw blood everywhere. It was just an explosion, it came out of nowhere," he said. "There are multiple injuries. I saw dismemberment, I saw blood everywhere. People are badly injured."
