Hitting back, CPI(M) general secretary Sitaram Yechury said on Monday that Prime Minister Narendra Modi "uttered untruths" to sharpen communal polarisation.
Modi at an election rally in West Bengal's Jhargram slammed Yechury for his "derogatory" remarks against Ramayana and Mahabharata.
"As is his wont, Modi distorted what was said in Bhopal where BJP has fielded a terror-accused. Like terror knows no religion, violent people can be found in all groups. Even epics Ramayana & Mahabharata speak of such people. To sharpen communal polarisation, Modi utters untruths," Yechury tweeted.
Modi said that it had become a "fashion for communists to use derogatory language against Hinduism".
Yechury had recently branded epics Ramayana and Mahabharata as specimens of Hindu violence.
