Mizoram government reiterates its opposition to the Centre's plan to fence the India-Myanmar border and scrap the Free Movement Regime (FMR), citing ethnic ties and concerns for refugees.
Mizoram's director general of police Anil Shukla held a high-level meeting on Sunday to assess the security arrangements, a statement said.
It said there is anger among Mizo youths, who are deeply anguished over the "barbaric and atrocious act of Meiteis" against Zo or Kuki ethnic people in Manipur.
Amid claims by locals that one of the shells fell in Mizoram, the Assam Rifles had on Thursday asserted that no explosion occurred in the state.
The government's assurance came amid reports of Meiteis fleeing the state following an 'advisory' by an ex-militant's association of Mizoram asking them to leave due to tension triggered by the viral video of two women being paraded naked by a mob in Manipur.
An order issued by the Home and Political Department's Commissioner and Secretary M S Mannivannan said in view of the joint statement by the representatives of the governments of Assam and Mizoram, "the travel advisory issued on July 29 is withdrawn".
At least five Assam Police personnel were killed while defending the "constitutional boundary" of the state with Mizoram and more than 60 people injured, including an SP, as the festering border dispute between the two northeastern states erupted into a bloody conflict on Monday.
The Assam government also decided to revoke an advisory issued earlier against travel to Mizoram, they said.
In a letter addressed to Union Home Secretary Ajay Kumar Bhalla, Mizoram Home Secretary Lalbiaksangi said that National Highway 306, the state's lifeline that connects it with the rest of the country, has been blocked in Assam since July 26.
Mizoram shares a 510 km long porous border with Myanmar's Chin state and most of the Myanmarese nationals who have taken refuge in the state belong to the Chin, also known as the Zo, community. They share the same ancestry and culture as the Mizos of Mizoram.
Police sources said the state forces exchanged fire for about 40 minutes.
The travel advisory is perhaps a first of its kind issued by any state government
Union Home Minister Amit Shah spoke to the chief ministers of Assam and Mizoram, Himanta Biswa Sarma and Zoramthanga respectively, and urged them to ensure peace along the disputed border and find an amicable settlement.
The situation is now under control in the area, which is on the border between the Kolasib district of Mizoram and Cachar district of Assam.
With this, the Congress has lost its last foothold in the north-east.
