Decoding Delhi Bomber Umar's Video: Radicalised Ready To Die And Kill

An undated and self-recorded chilling video of Dr Umar Mohammad, alias Umar-un-Nabi, the man behind the blast near Delhi's Red Fort that killed 15 people, has emerged - with the bomber speaking about suicide attacks in what looked like a "confident thought process", psychologist Namrata Ohri told NDTV.

Decoding Umar's body language in the video, Ohri said he did not make an eye-contact with the camera, and he kept moving constantly, indicating that he was not very comfortable with his body but was trying to convince the audience. It looked like the bomber had scripted what he said in the clip, the psychologist said.
