'Religious motives for bomb suspects'
The two brothers suspected of bombing the Boston Marathon appear to have been motivated by a radical brand of Islam but do not seem connected to any Muslim terrorist groups, US officials have said after interrogating and charging Dzhokhar Tsarnaev with crimes which could bring the death penalty.
Tsarnaev, 19, was charged yesterday in his hospital room, where he is in a serious condition with a gunshot wound to the throat and other injuries suffered during his attempted getaway.
