A former Indian Air Force employee, believed to be the leader of a self-proclaimed ISIS cell that the police said was involved in a train accident on Monday, was arrested today along with another man. The police said with today's arrests all eight suspected members of the terror module have been captured. One, 22-year-old Saifullah, was killed at a hideout in Lucknow after a 12-hour gun battle on Tuesday morning. Home Minister Rajnath Singh made a statement in Parliament today on the train attack and Saifullah, but did not mention an ISIS link.
