Modi was reacting to a speech made by CPI-M's Idukki district secretary M M Mani in which he stated that there had been instances of the party eliminating political rivals.
"When leader of a political party says that we murder our political rivals, it is dangerous to our democracy. Where is NHRC (National Human Rights Commission) ? We should raise our voice against such acts. Our workers keep giving their lives in Kerala," Modi said.
"Is Delhi government sleeping and what is Kerala government doing on the issue," Modi remarked.
"This language is same that of terrorists, Maoists and Naxalists," he further said.
Mani's speech had sparked a raging political row in the country with the Congress and BJP saying it exposed CPI-M's "politics of violence".
