"The incident took place between the forests of Maharabeda and Kaushalnagar villages this afternoon," state Director General of Police (DGP) Ramniwas told PTI.
Acting on a tip-off, the patrol party undertook a combing operation in the region since early morning. When it reached near the jungles of Maharabeda village, Naxals opened indiscriminate fire on them, killing three jawans of CAF 16 battalion.
"Two jawans died on the spot while another succumbed to bullet injuries while being taken out from the jungle," the DGP said.
Additional forces have been rushed to the spot. A search operation has been launched to nab the attackers, Mr Ramniwas said.
According to the DGP, few Naxals might have been injured or killed in the incident but their associates took them to the core forest region.
