Prime Minister Narendra Modi on Wednesday strongly condemned the dastardly Naxal attack in Gadchiroli district of Maharashtra in which 15 police commandos were killed, saying those responsible will not be spared even as the Congress party slammed the Centre for "failing to secure the country".

"Strongly condemn the despicable attack on our security personnel in Gadchiroli, Maharashtra. I salute all the brave personnel. Their sacrifices will never be forgotten. My thoughts & solidarity are with the bereaved families. The perpetrators of such violence will not be spared," the PM tweeted.
