The fight began early in the morning in Pallur jungle when a group of 20-25 Maoist ultras ambushed jawans of the SOG, the state's elite anti-Naxal force, who conducting a combing operation in the area.
In the ensuing exchange of fire, a woman Maoist and an SOG jawan, Gangadhar Dalai, died, Koraput Superintendent of Police Dipak Kumar said.
Hailing from Bargarh district, Dalai was critically injured in a claymore mine explosion and died in a hospital.
Another jawan was also seriously injured in the explosion and was being taken to a hospital at Vishakhapatnam in neighbouring Andhra Pradesh by a helicopter.
