Bombing Marathon Suspect Claims His Brother Was The Mastermind

The surviving suspect in the Boston Marathon bombings has indicated that his late older, not any international terrorist group masterminded the deadly attack, a U.S government source said.

Dzhokhar Tsarnaev, who has been hospitalized with a tube down his throat in recent days, communicated with investigators by writing and nodding.

The preliminary interviews with Tsarnaev suggest the two brothers fit the classification of self-radicalized jihadists, the source said.

Tsarnaev has conveyed to investigators that Tamerlan's motivation stemmed from Jihadist thought and the idea that Islam is under attack, and jihadists need to fight back, the source said on Monday.

The government source cautioned that the interviews were preliminary, and that Tsarnaev's account needs to be checked out and followed up on by investigators.
