Chhattisgarh CM Vishnu Deo Sai said the Naxalites are "frustrated with the ongoing Naxal eradication campaign in Bastar" after 8 District Reserve Guard (DRG) jawans lost their lives in an IED blast in Chhattisgarh's Bijapur on Monday. "They are perpetrating such cowardly acts out of frustration," he added. "My condolences are with the families of the martyrs," he further said.
