Boston, MA (Sports Network) - There were two explosions near the finish line of the Boston Marathon on Monday.
The two blasts marred Patriots' Day in Boston, transforming a celebratory atmosphere during one of the most prestigious races into a chaotic scene.
Police commissioner Edward Davis confirmed at a news conference that, at 2:50 p.m. ET, there were simultaneous explosions along the route of the Boston Marathon. "These explosions occurred 50 to 100 yards apart and each scene resulted in multiple casualties," Davis said.
The top runners in the marathon had finished just past Noon.
Davis didn't provide the number of casualties or people injured, but the Boston Police department did confirm on Twitter two fatalities, adding the blasts injured 23 more.
The Boston Globe is reporting that at least 125 people were injured and a person of interest in connection with the bombing was being questioned by authorities.
Davis added that, at about 4:12 p.m., the police department responded to a third incident at the JFK Library. The Boston Police department later tweeted that the preliminary investigation indicated the JFK Library incident may not have been an explosion. According to Davis, it may have been a fire.
President Barack Obama addressed a concerned nation during a news conference at 6:10.
"We don't yet have all the answers. ... We still do not know who did this or why," Obama said. "But make no mistake: We will get to the bottom of (this). We will find out who did this. We will find out why they did this. ... Any responsible groups will feel the full weight of justice."
Davis said that the bomb squad is examining parcels left along the race route.
"At this point, we have not found another device on Boylston Street," Davis said.
Davis urged people to stay calm and understand that this is an ongoing event.
