An alleged founder member of terror outfit Indian Mujahideen has spilled the beans on how the Mumbai train blasts in 2006 and the pre-diwali Delhi blasts in 2005 were executed.

"We purchased bags and pressure cookers in Bombay. On the day of the blast (11-07-06), all of us assembled and we filled seven cookers with explosives...We had planned the bombs to blast at 6:30 pm. Atif (another IM operative) gave me a bag which I kept in one of the local trains," said Sadiq Sheikh, arrested by the Mumbai police in October last year, during his interrogation, according to a video aired by CNN-IBN.
