"Deeply saddened by the news of the martyrdom of our police jawans in a cowardly attack by Maoists," Chouhan said in a tweet on the issue.
Maoists ambushed a security team killing 15 personnel, including 11 CRPF men and also a civilian in a chilling reminder of the 2010 massacre of 76 securitymen in the same area in the Sukma district of Chhattisgarh.
