Recently there was a clash between the residents of Lailapur village in Cachar district of Assam and the locals of Kolasib district of Mizoram.
Three Assam districts, namely, Cachar, Hailakandi and Karimganj share their border with three Mizoram districts including Kolasib, Mamit and Aizawl.
The border issue between Assam and Mizoram dates back to 1875 notification (Inner Line Regulation)which separated Lushai Hills (then Mizoram) from the plains of Cachar (Assam) and to 1933 when a boundary between Lushai Hills and Cachar was demarcated.
