After the death of at least 25 CRPF jawans by Naxals in Sukma, BJP MP Subramanian Swamy took to Twitter on Wednesday and proposed imposition of Emergency and Armed Forces Special Powers Act in Maoist-affected areas of Chhattisgarh. "We must now crackdown and do it in such a way that the Maoists will regret their wrongdoings," he added.
