Nayagarh, Feb 16: At least thirteen police personnel, including two women, and a civilian were killed in an attack by Naxalites in Orissa's Nayagarh District late on Friday night.

"Four policemen were also injured in the gunbattle that continued till around 12:15 am," he added.

One of the policemen killed in the attacks has been identified as ASI Nandpani Misra.

The injured have been shifted to SCG Medical College in Cuttack.

The Naxalites also reportedly looted the Nayagarh armory and the police training school and made away with large cache of arms and ammunition.

Before launching the attack, the Naxals announced that they would not harm the public as their target was the police.
