The decades-long Assam-Mizoram border dispute took an ugly turn on 26 July 2021 as a firing between police personnel of the two states saw six Assam cops being killed and several more injured. The border has long been a bone of contention between the two northeastern states and multiple talks facilitated by the Centre as far back as 1995 and as recent as 9 July 2021 this year made remained inconclusive.


  1. The firing on 26 July 2021 was preceded by incidents of bombing and encroaching on either side of the border.
  2. During the 9 July talks, Mizo miscreants were said to have conducted an IED explosion in Assam's Cachar district targeting a delegation of Assam government officials, including senior police officials, who were on a visit to oversee the construction of a road along the border, but no casualty was reported in the incident.
  3. This was met in retaliation with two back-to-back explosions on the other side of the border on 10 July 2021.
  4. Mizoram Home Minister Lalchamliana alleged that the crops of Mizo farmers were destroyed by Assam police personnel, who intruded into their territory.
  5. He demanded the Assam government give compensation to the affected farmers. He also stated that additional Mizoram police forces have been deployed in the affected areas to remove public fear and ensure a sense of normalcy.


  1. Three districts of the southern Assam's Barak Valley - Karimganj, Hailakandi and Cachar - share a 123-km-long border with Mizoram's Mamit, Kolasib and Aizawl districts.
  2. The border dispute between the two states is a long-standing issue. Assam says the boundary demarcated in 1933 notification should be maintained while Mizoram insists that the same drawn in the Bengal Eastern Frontier Regulation, 1875 should be the actual boundary.
  3. Violence broke out in October last year and in February this year, in which some schools were even allegedly bombed by miscreants from Mizoram's side.
  4. Mizoram, on the other hand, claimed that the schools were set up by Assam officials in their land.
