NEW DELHI, July 14 (Xinhua) -- Three people including a woman were killed Friday by Naxals rebel group in India's eastern state of Bihar, police said.
The killings took place in Barhat of Jamui district, 176 km south of Patna, the capital city of Bihar.
"We have recovered three bodies belonging to two youth and one woman near a dam that falls under Barhat police station," a police official said.
Local media reports said the Naxals suspected the slain to be the police informers and had placed a letter near the bodies.
Police have registered a case and launched a probe into the matter.
Naxalites are also known as "Maoists".
Maoist insurgency has its genesis in the violent left-wing rebellion that began in 1967 at village Naxalbari in Indian state of West Bengal.
Currently Maoists are active in more than a third of India's districts across central and eastern India.
India's former prime minister Manmohan Singh once termed the Naxalite movement as India's "greatest internal security challenge".
New Delhi has deployed several companies of its paramilitary forces to take on Naxals in their strongholds.
The insurgency reportedly has claimed more than 6,000 lives and rendered thousands of poor inhabitants homeless.
In April, 25 paramilitary troopers of India's Central Reserve Police Force (CRPF) were killed in Naxal attack in central Indian state of Chhattisgarh.
