WASHINGTON - Accused Boston Marathon bomber Dzhokhar Tsarnaev, who was found hiding in a boat days after the blasts, left a handwritten message describing the attack as retribution for US wars in Muslim countries, CBS News reported on Thursday.
The CBS News report, citing anonymous sources, said that Tsarnaev used a pen to write the message on an interior wall of the boat, where police found him bleeding from gunshot wounds four days after the April 15 bombing.
The note summed up with the idea that "when you attack one Muslim, you attack all Muslims," CBS News reported.
CBS News did not make clear how its sources knew the information and Reuters was not immediately able to confirm the report.
An FBI spokeswoman in Boston did not immediately return a call seeking comment.
