Boston bombs: Suspects 'planned more attacks'
Boston's Police Commissioner has said he believes the two brothers suspected of the marathon bombings were planning more attacks.
Ed Davis said the authorities found an arsenal of homemade explosives at the scene of their gunfight with the suspects.
There are now concerns that the surviving man may be too badly injured ever to be interrogated and there are questions about whether the FBI missed opportunities to avert the attacks.
