Raipur: Four Border Security Force (BSF) personnel were killed and two injured in an encounter with Naxals in Kanker district of Chhattisgarh on Thursday, police said.
The encounter comes a week before polling for the first phase of Lok Sabha elections is held in the state.
The skirmish took place around noon in a dense forest near Mahla village in Kanker district when a joint team of BSF's 114th battalion and the District Force was out on a search operation, police said.
"Four BSF troopers were killed and two injured in the incident," Deputy Inspector General (anti-Naxal operations) Sundarraj P told reporters.
The patrolling team had launched the operation from the BSF's Mahla camp, located around 250 from Raipur, he said.
When the security men were advancing through a forest patch, a group of naxals fired at them, leading to a gun battle, he said.
