Boston bombings suspect Dzhokhar Tsarnaev left a hand-written manifesto inside the boat he was hiding in during the pursuit, according to CBS News.

      The scribblings, done with a marker on the interior side of the boat, praised late brother Tamerlan as a martyr, CBS News quotes its sources as saying.

      The main cause of the attack that killed 3 and wounded some 260 during the Boston Marathon was a revenge for U.S. military campaign in Afghanistan and Iraq, the note inside the boat allegedly reads.

      ‘When you attack one Muslim, you attack all Muslims,’ it also said, according to CBS News sources.
