Without naming BJP, Akhilesh Yadav accused some political parties of trying to raise communal tension over some incidents that resulted in the Muzaffarnagar violence.
He said the demolition of Babri masjid some years ago was a black chapter in the country's history and was meant to harm communal harmony.
“At present, it seems that some of the main political parties are trying to dangerously harm the communal harmony of the state in view of 2014 general elections. Efforts are on (by them) to polarise people of the state,” Yadav said.
