A bomb goes off in a bakery near a meditation centre in Pune, in western India, in the first major attack since the Mumbai bombings more than two years earlier.
Two groups calling themselves the Laskhar-e-Taiba Al Alami and the Mujahideen Islamic Muslim Front claimed they carried out the attack. But Indian anti-terrorism investigators arrested four people believed to be members of the Indian Mujahideen, a home-grown Islamic militant group. Indian authorities say the group is a militant front of the Students Islamic Movement of India, which they allege has close links with Lashkar-e-Taiba (LeT), a Pakistan-based militant group. The group gained attention when it claimed responsibility for a series of attacks in July 2008 in the western city of Ahmedabad that killed more than 45 people. The group's emails claiming responsibility for various attacks express anger at the treatment of Muslims in Hindu-majority India
Gunmen launch a co-ordinated series of attacks at several central locations across Mumbai and take hostages at two luxury hotels. The attacks spanned three days and included one of the busiest railway terminals in the country.
The attacks were planned and carried out by LeT militants based in Pakistan. Only one of the 10 men who carried out the attacks was captured alive. LeT was banned in Pakistan in 2002. Analysts have said LeT was created with the help of Pakistan's intelligence agencies in the 1980s to act as a proxy fighting force in Indian Kashmir. Among its goals is the establishment of Islamic states in regions bordering Pakistan.

The area is wedged between Bangladesh, Bhutan, China and Burma, with only a thin corridor connecting it to the rest of India. It has been a hotbed of separatist violence, where more than 10,000 people were killed in the previous decade. Among the groups suspected of carrying out the attack is the United Liberation Front of Asom (ULFA), which was banned by the Indian government in 1990. The group has been fighting for independence for Assam. The group dropped its demand for independence as a condition for talks with India in January 2010.

The group was founded in 1977 to establish an Islamic state in India. The Indian government banned the group in 2001. Some analysts believe the group also operates under the name of Indian Mujahideen.
