Delhi Chief Minister Arvind Kejriwal on Wednesday condemned the police action on students of the National Institute of Technology (NIT) in Srinagar, saying the government "must stop this immediately"."Lathicharge on students in Srinagar is highly condemnable. BJP-PDP must stop this immediately," the Aam Aadmi Party (AAP) chief said in a tweet."In Kashmir, the Bharatiya Janata Party (BJP) is beating those saying 'Bharat Mata ki Jai', and in the rest of the country those who don't say it," Kejriwal added.Tension gripped the NIT-Srinagar campus late on Tuesday after a group of non-Kashmiri students clashed with police.An official said police then resorted to a baton charge to disperse the students, in which seven of them sustained minor injuries.The campus atmosphere has been surcharged ever since Kashmiri students celebrated India's defeat to West Indies in the World T20 semi-final on March 31. The non-Kashmiri students objected to this, leading to a clash and subsequent tensions.
