"We have a number of 176 casualties that presented at area hospitals," Boston Police Chief Ed Davis told reporters, adding that 17 people were in critical condition.
Earlier, Massachusetts Governor Deval Patrick had placed the number of injured at more than 150.
The good news was that there are no known additional threats following the bombing, an FBI official said Tuesday.
FBI Special Agent Rick DesLauriers told reporters in the aftermath of Monday's attack that while investigators were fanning out across Boston, there was "no known imminent physical threat at any location" in the area.
Still, he stressed, the FBI was leaving no stone unturned. "It will be a worldwide investigation. We'll go to the ends of the earth to identify the subject or subjects who are responsible for this despicable crime and we will do everything we can to bring them to justice," DesLauriers said.
The agent also said the US Federal Bureau of Investigation was "not aware of any threat information prior to the marathon."
Massachusetts Governor Deval Patrick, meanwhile, said only two bombs were used, and no other other unexploded devices had been found despite earlier reports to the contrary.
"It's important to clarify that two and only two explosive devices were found yesterday," Patrick said. "Other parcels -- all other parcels in the area of the blast have been examined. No unexploded bombs. No unexploded explosive devices (were) found."
He said over 150 people were injured, some of them gravely.
"Our thoughts go out to all of those injured and killed," he said.
