NYC blast suspect Akayed Ullah aimed to avenge Muslim deaths, source says

The Brooklyn man who allegedly detonated a crude pipe bomb in a New York City subway station told investigators he did it in the name of ISIS to avenge the deaths of Muslims around the world, a senior law enforcement official told NBC News. Akayed Ullah, a 27-year-old Bangladeshi immigrant, said he consumed terrorist propaganda and learned how to make the explosive device through online instructions, the official said. There is no evidence Ullah had any contact with ISIS but he told investigators he watched the group's material online.
