Police had received a tip off of presence of naxals in the region after which a team of security forces was dispatched to nab them. When the team reached between Kamkanar and Poddejojer villages, the ultras opened indiscriminate firing at them, Additional DG (anti-Naxal operations) R K Vij told PTI.
Post the attack by naxals, police opened retaliatory firing, the senior officer said, adding, the ultras fled the spot after the skirmish which lasted for about an hour.
When police inspected the area, bodies of four naxals, arms and ammunition like hand grenade were recovered from the site, Vij said.
As many as seven naxals have been killed so far this month in Bijapur. Earlier, an LOS commander was killed on January 6, while two women ultras were gunned down in a joint operation of the state and Maharashtra Police on January 11.
