NEW DELHI, 27 July 2021, (TON): A senior politician said that at least seven people, including six police officers, were killed and more than 70 hurt on Monday in clashes between two Indian states, as a weeks-long territorial dispute in the country's northeast turned deadly.

Tensions on the border between Assam and Mizoram have been elevated since last month, when Assam's police allegedly took control of the hilly area of Lailapur, accusing Mizoram of encroaching on the territory.

The violence highlights the long-standing inter-state boundary issues in the region, particularly between Assam and neighbouring states.

Assam Chief Minister Himanta Biswa Sarma told media "we have lost six of our policemen and a civilian along the Assam-Mizoram border when miscreants from Mizoram opened gunfire."

In response, Mizoram's home minister, Lalchamliana, said “in a statement Monday's violence began when Assam police encroached on its territory."

The two state heads, Assam's Sarma and Mizoram's Zoramthanga have each blamed the other side for the violence, appealing on Twitter for India's interior minister Amit Shah to intervene.

Both shared videos of clashes on a thin strip of road running through hills where armed police and civilians can be seen fighting with wooden batons.

Prime Minister Narendra Modi's Bharatiya Janata Party (BJP) is in power in Assam, while the Mizo National Front (MNF), a constituent of the BJP-led North East Democratic Alliance (NEDA), is ruling in Mizoram.
