Bhubaneswar, Aug 12 - At least three Maoists were killed Wednesday in a gunfight with police in Orissa's Rayagada district, officials said.

A joint team of Orissa and Andhra Pradesh police fatally shot the militants in a forested area under Chandili police station, about 45 km from the district headquarter of Rayagada, Ashish Kumar Singh, district superintendent of police, told IANS.

'Although no policeman was hurt we fear some Maoists may have sustained injuries,' he said, adding that three rifles, a few hundred rounds of ammunition and some bags containing Maoist literature were seized from the spot.

Maoists are active in more than half of the state's 30 districts. The district headquarter of Rayagada is located 390 km from state capital Bhubaneswar.
