Mother of the Tsarnaev Brothers Continues to Insist They Are Innocent

Zubeidat Tsarnaeva believes her sons were not involved in the Boston Marathon bombing

BOSTON (AP) -- The angry and grieving mother of the Boston Marathon bombing suspects insists that her sons are innocent and that she's no terrorist.

But Zubeidat Tsarnaeva is drawing increased attention after federal officials say Russian authorities intercepted her phone calls, including one in which she vaguely discussed jihad with her elder son. In another, she was recorded talking to someone in southern Russia who is under FBI investigation in an unrelated case, U.S. officials said.
