At least six personnel of the Assam Police were killed in firing by miscreants from neighbouring Mizoram on Monday as violence escalated along the inter-state border in the Cachar district, Chief Minister Himanta Biswa Sarma said.

A senior Assam Police officer, who is still inside the forest amid continuous firing from across the border, told PTI that at least 50 personnel, including Cachar Superintendent of Police Nimbalkar Vaibhav Chandrakant, were injured in firing and stone-pelting.
