According to police, the incident took place near Army Cantonment in the eastern part of city where members of the two communities indulged in stone-pelting over a petty issue.
"Despite several warnings people did not stop hurling stones, so police fired two rounds of tear-gas shells," said Inspector J M Patel.
"Patrolling in the surrounding area has been increased and additional police force has been deployed," he said.
No arrest or detention was confirmed by the local police station officials.
