The gunfight broke out Wednesday close to India-Myanmar international border at New Samtal village in Chandel district, about 130 km south of Imphal, the capital city of Manipur, reports Xinhua.
According to the Indian army, the paramilitary troopers were working under their command.
"During the operation, the troops were fired upon by suspected cadres to which they quickly reacted, redeployed and retaliated in a calibrated and measured manner. In the ensuing firefight, 10 cadres were killed and a sizeable quantity of arms and ammunition have been recovered," an Indian army statement said.
Officials said the operation was underway in the area.
