Violence began on Friday night when an Indian Reserve Battalion (IRB) team on routine patrol was fired upon by armed Kuki militants near Chassad Kuki village.
The Bailey bridge across the Namban River — which connects Kamjong to Sahamphung subdivision via Chatric Khullen and Chatric Khunou — was demolished in a powerful explosion on the intervening night of 21–22 July 2026.
