The clashes erupted as Sinhala students brought in Kandyan dancers to a 'welcome party' at the university, held for first year students at the campus.
Discussions had taken place last week over the dances that were to take place. On Saturday morning however, tensions grew as Sinhalese students clashed with traditional Tamil musicians playing at the ceremony, as they attempted to take over proceedings.
"They were holding sticks, iron rods broken pieces of furniture,” he added, as they proceeded to attack the Tamil students.
At least 10 students have been admitted to hospital in the clashes, as Sri Lankan police descended onto the scene. Troops from the Special Task Force closed off the area, with military intelligence operatives also reportedly deployed in the area.
Sinhalese students were swiftly escorted by Sri Lankan police back to their homes or to Jaffna Hospital to receive treatment.
Tamil students meanwhile have been more cautious to seek treatment. "If a Tamil student was to go to the hospital with injuries, staff will know it was because they were attacked," one eyewitness told the Tamil Guardian.
"Then it's only a matter of time before police harassment begins."
Meanwhile officials at Jaffna University declared the campus would be shut down for at least two weeks due to damages sustained and in a bid to help ease tensions on campus.
