BDR troopers opened fire on Indian villagers who had gone for cultivation in an 'adverse possession land' near Noljuri in Jaintia Hills, BSF sources said.
A lady school teacher was injured in the firing after which she was evacuated to the Dawki border outpost, they said.
The BSF maintained restraint and evacuated the civilians from the line of fire.
Later, the BDR also opened fire at three other places ? Ratangtila, Dawki and Muktapur, the sources said.
The incident came a day after BDR erected a red flag on land held in 'adverse position' at Amlympiang near Noljuri where the first firing took place. The flag was erected to prevent Indians from entering the area, the sources said.
