UPDATE: 4/15/13 05:15 p.m.

Boston police say no suspect has been taken into custody in connection with the explosions near the finish line of the Boston Marathon.

Police Commissioner Edward Davis also says that the fire at a library a few miles away and more than an hour later doesn’t appear to be related to the explosions at the race on Monday. He says the fire may have been caused by an incendiary device.

Authorities say the blasts killed two people and injured at least 73.

Police say it’s too early to get into specifics about the nature of devices or whether shrapnel was involved.

At least two explosions rocked an area near the finish line of the Boston Marathon Monday afternoon.

The explosions occurred just a few seconds apart on opposite sides of the street.

According to witnesses, the first explosion left a huge plume of smoke hovering over the entire area.

Both explosions occurred around 2:45 pm, just about an hour after the first runner crossed the finish line.  The race was stopped shortly after the blasts.  Approximately 27,000 runners competed in the race.

Witnesses said several victims lost limbs in the explosion, and authorities are saying there was at least six reported injuries so far.

Many of the injured appeared to be spectators, and they were transported to Massachusetts General Hospital for treatment.

There have not been any deaths reported at this point.
