Boston Marathon bombing suspect Dzhokhar Tsarnaev informed investigators that he and his brother were not directed by a foreign terrorist organization. Instead, they were “self-radicalized” and motivated to kill, in part, by U.S. wars in Iraq and Afghanistan, the Washington Post reported.

The 19-year-old also acknowledged his role in the attack while being questioned by investigators in his hospital bed, the report said. Tsarnaev, who has a gunshot wound to the throat and was sedated, responded in writing. He also suffered gunshot wounds in the head, neck, legs and hand during a late-night shootout in Watertown, Mass.

Meanwhile, Tsarnaev's condition is improving, the FBI said on Tuesday. The college student, who had been listed in serious condition at Beth Israel Deaconess Medical Center since his capture on Friday, is now in fair condition, the bureau said.
