Condemning the attack on students and teachers at JNU, Union minister Prakash Javadekar slammed the Congress, AAP and the Left parties, accusing them of creating an atmosphere of unrest in the country.

'I condemn the violence which took place last night in JNU. Some elements from the Congress, Aam Aadmi Party and the Left are deliberately trying to create an atmosphere of violence and unrest in the country, especially in universities. This should be investigated,' Javadekar tweeted.

Also, in reference to the violence inside JNU, Union miniser Smriti Irani said campuses should not be made a 'political battlefield'.

'I had said it earlier and reiterating it now that educational institutions should not be made 'rajiniti ka akhada' (political battlefield) as it affects the life and progress of our students,' Irani told reporters in Amethi when asked about the violence in the campus.

'I hope students will not be used as 'rajnitik mohre' (political tools),' the Amethi MP said.

'A probe has started in the matter and it is not justified for me to comment on it as I am in a constitutional post,' she added.

On Sunday night, violence had broken out inside JNU when masked men armed with sticks and rods attacked students and teachers and damaged property on the campus, prompting the administration to call in the police.

At least 34 people, including JNU Students' Union president Aishe Ghosh, were injured as chaos reigned on the campus for nearly two hours. The injured students taken to AIIMS and were discharged later on Sunday.

Incidentally, Irani was the human resource development minister in 2016 when the premier university was embroiled in a row over 'anti-national' activities in which then JNUSU president Kanhaiya Kumar was arrested on charges of sedition.
