Police is now probing a possible link between the men who carried out Mumbai's terror attacks and the Indian Mujahideen (IM), the group that has been responsible for several blasts across the country. At the outset, the links seem tenuous. Indian Mujahideen members were seen as homegrown bombers with many of their activists in jail. On the other hand, the 26/11 terrorists have clearly been established as Pakistanis.
