New Delhi, Sep 23 (IANS) Uttar Pradesh Chief Minister Akhilesh Yadav Monday said some "prominent political parties" were to be blamed for the recent violence in Muzaffarnagar.

"It looks at present that in view of the 2014 Lok Sabha elections, some prominent political parties are making dangerous efforts to mislead the public and spoil communal harmony," Akhilesh Yadav said at the National Integration Council (NIC) meet here.

"There is an attempt to polarise people in the state," he said, without naming any party. 

At least 48 people were killed in communal clashes that broke out in Muzaffarnagar Sep 7.

Yadav also said that hate material on social media needed to be controlled.

"There is no effective mechanism at present to stop hate material on social media. Service providers should have capacity to identify people who send such material," he added.
