1966 Lumding train bombing

Background

For years prior to 1966, the Indian state of Nagaland had experienced violence between Naga nationalists and the Government of India, with many Naga engaging in guerrilla activities against the government. Roughly two months before the Lumding bombing, a separate train bombing had killed 43 people, with Naga militants later found responsible for that earlier attack.

The Incident

On the evening of April 20, 1966, a time bomb planted by Naga separatists exploded in a third-class compartment of Coach No. 3583, part of the 20 Down Tinsukia-New Jalpaiguri passenger train, while it was standing at Lumding railway station on the North-East Frontier Railway in Assam. The explosion blew off the roof of the rear portion of the coach, causing heavy casualties among both passengers in the train and people on the platform. The Minister of State for Railways, Dr. Ram Subhag Singh, characterized the incident as an act of "sabotage."

Casualties and Response

The bombing killed 57 people and injured an additional 72. Railway and local authorities began rescue and relief efforts promptly, and medical relief was provided swiftly. Ex-gratia payments were arranged for the injured, although the Indian government was accused of not taking the matter seriously enough.

Three days later, on April 23, 1966, a similar explosion occurred at Diphu Railway station, again involving the Tinsukia-New Jalpaiguri passenger train. That incident killed 41 people and injured 81 others. The Minister of Railways, S. K. Patil, expressed regret over the two explosions and outlined the government's immediate relief response.

Investigation

Dr. Ram Subhag Singh told Parliament that the bombings appeared to be acts of "well-organized sabotage," and that the explosives used were of high power and possibly of foreign manufacture, indicating a clear case of sabotage. Authorities made only two arrests in connection with the Lumding and Diphu incidents combined, and this limited response drew heavy criticism from commentators.

Reactions and Aftermath

The bombings prompted concern in the Lok Sabha, where members questioned the government's measures to prevent such attacks. The Minister of State for Railways assured Parliament that steps such as pilot patrols and carrying security guards on trains had already been implemented following previous incidents, and the possibility of checking passengers and luggage was also discussed. The Minister of External Affairs, Sardar Swaran Singh, raised the matter in Parliament as one of urgent public importance. Indian Prime Minister Indira Gandhi, who was at the time engaged in negotiations with Naga leaders, expressed sadness over the Lumding tragedy. The bombings drew attention to the ongoing tribal rebellion in eastern India, with Naga tribesmen implicated in the attacks.
