Boston Marathon Blasts Kill 2, Police Say

BOSTON — A series of explosions was reported near the finish line at the Boston Marathon on Monday, leaving two people dead and at least two dozen injured, according to the Boston Police Department.

A third explosion was heard just before 4 p.m., about an hour after the first two blasts. The police were apparently aware of that device before the explosion occurred.

The blasts took place about four hours after the start of the men’s race, which meant that there were still several thousand runners yet to finish the race. One senior counterterrorism official said it was too soon to tell whether the explosions were related to terrorism.

The Boston police confirmed they were looking into the explosions, but made no further comment. Another senior United States government official said that the Boston police and the F.B.I. said they had received no reports in recent days about a threat of an attack on the marathon and that there was no warning on Monday.
