A group calling itself the Deccan Mujahideen claimed responsibility for the Nov. 26 Mumbai attacks, in which militants armed with AK-47s and grenades attacked hotels, a cafe, a cinema, a train station, hospitals and police forces. All attacks were focused on Western and economic targets, revealing a dramatic shift in tactics and targeting from Islamist militant groups operating in India. (click image to enlarge) Islamist militant groups in India have not used the name Deccan Mujahidden before, but the new name does not necessarily mean a new group has arrived on the Indian militant scene. India has a vibrant history of Islamist militancy. The traditional groups operated under the banners of the Students Islamic Movement of India (SIMI), Lashkar-e-Taiba (LeT) or Harkat-ul-Jihad e-Islami (HUJI). These groups would both collaborate and compete with each other, but they all shared a lifeline that started in Islamabad with Pakistan's Inter-Services Intelligence (ISI) agency.
