In July 2006, seven blasts in separate locations on local trains killed 186 people. Indian officials blamed the attacks on Pakistan-based militant group Lashkar-e-Taiba and domestic group Students Islamic Movement of India and said they were acting on behalf of Pakistani intelligence agency Inter-Services Intelligence (a claim that Pakistan denied), according to a BBC report from 2006.
The incident brought Indian-Pakistani relations to a low point, with Pakistan furious with India for placing blame on the Pakistani government.
