the Indian Army, eventually succeeded in pushing the movement underground. In 1985, Sikh terrorists bombed an Air India flight from Canada to India, killing all 329 people on board Air India Flight 182. It was one of the worst terrorist act in Canada's history. The ending of Sikh militancy and the desire for a Khalistan catalysed when the then-Prime Minister of Pakistan, Benazir Bhutto, handed all intelligence material concerning Punjab militancy to the Indian government, as a goodwill gesture. The Indian government used that intelligence to arrest those who were behind attacks in India and militancy. The ending of overt Sikh militancy in 1993 led to a period of relative calm, punctuated by militant acts (for example, the assassination of Punjab CM, Beant Singh, in 1995) attributed to half a dozen or so operating Sikh militant organisations. These organisations include Babbar Khalsa International, Khalistan Commando Force, Khalistan Liberation Force, and Khalistan Zindabad Force. 1991 Punjab killings The 1991 Punjab killings was a massacre of train passengers that occurred on 15 June 1991 in the Ludhiana district of the Indian State of Punjab, where Sikh Khalistani militants killed at least 80 to 126 passengers travelling in two trains. The militants stopped the two trains about a kilometre from Ludhiana station by pulling their emergency cords, triggering emergency brakes. They proceeded to open fire inside the trains at around 9:35 p.m. (IST), killing at least 80 passengers. On the second train, the Dhuri-Hisar passenger train, the militants fired indiscriminately.

The attacks came less than five hours after polling closed in a national election already marred by violence and interrupted by the assassination of ex-Prime Minister Rajiv Gandhi around a month prior.
