A woman Naxal was killed and two police personnel were injured in an encounter in Chhattisgarh's insurgency-hit Narayanpur district on Wednesday morning, an official said. The exchange of fire broke out in a forest under Chhotedongar police station limits around 8 am, when a joint team of the District Reserve Guard (DRG) and Chhattisgarh Armed Force (CAF) was out on a counter-insurgency operation, Narayanpur Superintendent of Police Mohit Garg told PTI. When the patrolling team was cordoning off the forest close to a hillock near Kademeta police camp, the ultras, who had laid an ambush, detonated IEDs (improvised explosive devices) and opened fire at the security personnel, leading to the gun-battle, he said.
