BOSTON — A senior U.S. intelligence official says two more explosive devices have been found near the scene of the Boston marathon finish line where two bombs detonated earlier this morning.
The first two explosions that killed at least two people and injured dozens more appeared to be bombs. However it is not clear if the second set of devices — which were being dismantled — are bombs, according to Time.
The official, who spoke on condition of anonymity, said the motive for the attack and who is responsible is not yet clear.
A third blast was later reported at JFK Library about 5 miles away,
